Remove from original feed?

The plugin should not add the feed items to the default feed. In fact it adds a feed of its own, with the name of the setting “Custom feed URL”.

Perhaps you left this option blank?

Hello, I did not touch the default setting for custom feed URL. I also checked so the new feed worked, and it did.

Actually, I didn’t change any defaults or styles.

Unfortunately I cant install it again to show it because the web is live and I have things like auto posting to social networks and newsletters connected with my normal feed (had to desperately edit/delete on like 15 external medias when it started pumping out new feed items).

Have I discovered a new bug or missed something?

I activated the plugin again for a short time and took some screens.

Before activating the plugin:

After activating the plugin:
https://swesecnews.se/tmp/after.png

And Custom Feed URL settings:

I see.
Can you kindly send us a screenshot of all your settings?
And just to check, have you ever added any of our filters to your theme?

Well, since I have uninstalled and reinstalled the plugin all the settings are default I presume.

No, I have not installed any filters.

I’m confused now.
In your first message, you said the plugin was adding the RSS items in the feed, but in the before and after images you sent, I am seeing that the “after” is actually shorter.

Can you kindly send us your System Info from the Debugging page of the plugin?
If you still do not wish to activate the plugin, instead send us a list of the plugins you have activated and your WordPress, PHP and WP RSS Aggregator versions. Any other information you can give us is is also useful.
