The feed on my site suddenly stopped working and is returning a blank page. It worked on Friday, but didn't on Monday. No fundamental changes were made over the weekend, just a few posts were added. I've uninstalled and reinstalled plugins to no avail. I've removed all the posts that were made over the weekend in case one of those was causing the issue....still no feed. The feed does work in a staging/testing environment however.
My feed URL is http://butlerradio.com/feed
Any ideas/suggestions would be appreciated.
First thing to do is eliminate the possibility of a conflict. You can do that by logging in via FTP and renaming your plugin directory (plugins to plugins-off). If that resolves the issue you know you have a plugin that is causing a conflict. Reactivate one by one until the problem occurs to discover your bad actor.
While you are at it, make sure that all your plugins are tested and compatible up to 5.1.1 too.
If the issue persists, it could be your theme, try switching to the default Twenty Nineteen theme to see if that resolves the issue. If it does, it is an issue with your theme.
Whenever WordPress does not behave as it should, and no code has been modified, a conflict is usually the culprit.
Thank you, yes I De-and Re- activated all plugins to no avail. The theme doesn't appear to be the issue either. What confuses me is that in the staging environment it works fine...making it difficult to troubleshoot.
