WP RSS Aggregator is a plugin for WordPress that lets you import and display RSS feeds. The Plus, Pro and Elite plans include a “Feed to Post” feature, which allows you to import feed items as WordPress posts or any custom post types, integrating them seamlessly into your site.
To access the premium features, you need to install the Premium version of the plugin. You can download it from your account or from the link in your purchase confirmation email. For step-by-step instructions, please refer to this guide.
Broken characters in titles can occur for various reasons. First, ensure your hosting provider supports the latest stable PHP version. If that doesn’t resolve the issue, you can apply the following filter in WordPress:
add_filter( 'wprss_ftp_converter_post_title', 'my_unicode_title', 10, 2); function my_unicode_title($title, $source) {
return html_entity_decode($title, 0, 'UTF-8');
}This filter decodes non-ASCII characters encoded as HTML entities during import. After adding the filter, delete the affected posts and re-fetch the feed source.
Here’s how to add the filter to your WordPress site:
1. Copy the code above.
2. Go to your WordPress dashboard.
3. Navigate to Plugins > Add New.
4. Search for “Code Snippets,” then install and activate the plugin.
5. Go to Snippets in your dashboard menu.
6. Click on Add New.
7. Add a Title for the snippet.
8. Paste the copied code into the Code section.
9. Optionally, add a Description or Tags.
10. Click Save Changes and Activate.
We offer multi-site licenses, so you don’t need separate ones. Note that you can use the same license on a development or staging site and your live site.
There are times when you will want every source’s import in Aggregator to re-fetch all the content you have already imported. This will replace the existing imported content with that which is now available in the RSS feed. For example, if your source has a tendancy to update the content of articles after publishing, you may want to always have the latest version available on your site.
To do this, in the Source editor, go to Settings > Update Strategy, and enable the Keep items up-to-date option.
This issue might occur for several reasons. Before proceeding with troubleshooting, ensure the following:
Feed Sources: Have you added any Feed Sources in WP RSS Aggregator? If not, add a feed source following this guide.
Feed Items: Check if your Feed Sources contain any feed items to import. Edit the Feed Source and make sure the Preview section shows feed items that fit your set parameters, like age limits.
Imported Items: Does the Sources page display a number of imported items on the right-hand side for each source? If not, consider potential issues outlined in this help documentation.
Should the problems persist, please contact our support team.
If everything is correctly set up and the issue persists, feed items should display through the
No, there is no specific penalty from Google for duplicate content. However, it can affect your site’s authority and rankings if not handled properly. Google focuses on providing the most relevant search results rather than penalizing sites for duplicate content. It’s best to create unique, high-quality content and follow SEO best practices to avoid potential issues. Read more about this in our blog post .
The “Force Full Content” feature may not import all content due to several limitations:
HTML Structure: The Full Text algorithm relies on reading HTML markup to determine content. If a page’s structure is incorrect or lacks semantic clues, it may not identify all the content to import.
Large Feeds: The script is not optimized for processing large feed counts (100+ items) at once, leading to potential import issues.
Site Inaccessibility: Some sites use restrictions like token authorization, preventing content access. In these cases, only RSS feed content can be imported.
Featured Images: If the featured image isn’t within the post content or RSS feed, it may not be imported, as the service reads only post content.
Adjusting feed schedules and understanding these limitations can help mitigate such issues.
When feed items or posts are not automatically being imported, but they are imported when you manually click on the Fetch items action link, the reason is, more often than not, cron job issues.

In v4, premium license holders had license keys for individual add-ons as well as a main plan license key. The latter was never used and you had to activate a license key for each add-on in your plan. As of v5, the add-on license keys are no longer needed and you only need the main license key. If you go to your Aggregator account , you will notice the add-on license keys are marked as “Legacy”. Once you’ve upgraded to v5, follow these instructions to activate your plan’s license.

If you’re using the Feed to Post feature, you don’t need the shortcode or block. Feed items are imported as WordPress posts or custom post types and are displayed by your theme, page builder, or any method you choose.
Yes, both the core plugin and the premium plugin are PHP 8 compatible.
WP RSS Aggregator works great with any well-coded WordPress theme or page builder.
Nowadays, we are seeing many top themes becoming popular, be it Avada, Divi, Elementor, StudioPress themes, and many more. All of these are known to work well with WP RSS Aggregator.
If anyone comes across an issue when using a theme, please contact us to report the issue along with as many details as you can provide. We do not guarantee that all WordPress themes will work well with WP RSS Aggregator. For this reason, if an issue is found, it will be fixed at our discretion.

Should you need customization of our plugin or a theme, contact our trusted partners here.
Some websites block their content from being displayed in windows on domains other than their own, including lightboxes. Browsers honor this setting as a security measure. For example, a payment gateway might do this to prevent scams. As a result, feed items from these sites might not work with WP RSS Aggregator’s lightbox link behavior. This is a limitation from the source sites, and their preferences must be respected.
There are several methods for locating a website’s RSS feed. Click here to learn more.
No, WP RSS Aggregator only imports RSS feeds, not JSON feeds.
No, code customizations are outside the scope of our support services.
However, we have partnered up with Codeable for all types of customization work, so if you’re interested in a customization you can get in touch with them here.
This applies to all forms of customizations, from CSS changes to adding custom features.
Our plugin does not currently offer an option for you to enter authentication information for a feed source.
However, if the feed uses basic HTTP authentication, you can simply add the user and password to the feed URL as shown below:
Before: http://somesite.com/feed
After: http://user:pass@somesite.com/feed
Unfortunately, WordPress.com does not allow our plugin to be used on any sites they host.
This is explained on their website here: https://en.support.wordpress.com/incompatible-plugins/
As they explain it:
We know it can be tempting to automatically import content from around the web using content scrapers. We’ve found that these sorts of plugins are not a good fit for sites hosted here at WordPress.com and ask that you refrain from using them as not only do they place unnecessary loads on our infrastructure, automated posting is often seen as spam and is generally unwanted.
Although our plugin can be used for many great purposes and we’ve had no such issues with any other top WordPress hosting companies, this is something out of our control. We have reached out to the WordPress.com team, however, they have no plans of changing their reasoning.
The impact of our plugin on the performance of your website depends on your usage of the plugin and on the resources that are available on your server.
Some of our customers have hundreds of feed sources importing thousands of items without a significant decrease in speed. Generally, the amount of resources consumed is directly proportional to the number of feed sources you have active, the number of feed items being imported, and the number of items already imported; all that times the frequency of imports.
As a preventative measure, if you are planning to do a lot of importing, we recommend a hosting plan with at least 128M of memory available for PHP. Also, please bear in mind that in order to utilize available memory resources, the WordPress memory limit has to be adjusted accordingly.
We also recommend staggering the importing of feed items on your site, as explained here.
There is no limit for the number of feed sources you can import content from.
Having many (50+) feed sources should not present any problems in itself. However, pulling in posts from many sites is bound to put your server under some stress, so you might want to consider using a hosting solution that goes beyond your typical shared host. Check out our dedicated page for hosting recommendations.
Yes, Aggregator is compatible with WordPress Multisite.
If you only want to activate Aggregator from your main site, then you just need a Single-Site license. On the other hand, if you plan to activate Aggregator on more than one subsite/subdomain, then you’ll need more than a single site license.
The latter usually applies when you host multiple client sites in a multisite, which means each one will require a separate license key in order to receive updates and support. If used only on the main site to distribute feed items or posts to the subsites, then a single-site license key is enough.
Please do note that the site license refers to the number of WordPress sites you will activate this license on. It does not refer to the number of feed sources you can import from. In fact, the number of feed sources per site is unlimited.
