CREA DDF blacks out in latest WordPress

[responseit]

I'm not sure if this problem lies here in WP or on the DDF's side, but I do know that if I force lower the version of WordPress, my feed works, but in 5.6 it shows a black screen and nothing else, any time you click anywhere on a page where the DDF is running.

So right now I have sites with CREA DDF feed that are running lower WP versions because it is incompatible with 5.6 to the point that it is completely useless.

Note, I have used two different plugins for the DDF on two different sites, with the same result, so I don't believe the fault lies with the plugin. The WP version that does function as expected is 5.5.3.

If you advise me to approach the plugin developers or DDF providers I certainly will, but the fix of downgrading was a clue to 5.6 being the culprit.

Thanks!

Hello @responseit and welcome to Trac. Thank you for the ticket. Sorry to hear you have trouble with special feeds after updating to latest WordPress.

This is, however, a tool for making WordPress core, not for support. Even if you don't believe the problem is with the plugin(s), the plugin developers, or a plugin support forum, must be the first party to consult when trying to get to the bottom of this.

Since no one has responded here yet, it's a sign that nobody here has a guess of any core change that might cause this. So my advice is to go to plugin developers. If any has any clue to this being a core bug, come back here with some actual coding examples that did work, but now doesn't, plus debug information. For core developers to take action requires some simple demonstration that there is actually a core bug.

You may start here ​https://wordpress.org/support/forum/how-to-and-troubleshooting/ as the people there probably are the best to point you in the right direction, even if a core bug might be the root cause. Each plugin on the repo also have a dedicated forum.
