@sergechabert, @saharavis – FYI you should really start new threads, but in general this has never been an issue on our end. Every instance of these reports has been a theme or another plugin that modifies the menu editor in ways that are no longer compatible as of WP core updates earlier this year.
Our plugins code is and always has been written in a way that is deemed “the most compatible” way at the time, including at this time.
BUT any other plugin or theme can do things in a non-compatible way which will result in breakages for either them or us. Nothing we can do about it but point the finger honestly, no code changes on our end would correct the issues created by code on their end.
There are 2 common issues:
1. They do things in a way that our code never runs, as such no change would allow our code to do something differently if it doesn’t run in the first place.
2. They didn’t update from the old “compatible” method for the new WP core updates, resulting in our fields being duplicated.
Use the Health Check plugin’s troubleshooting mode to identify the culprit, then report it to that plugin/theme’s author and hope for the best, as the only other options are either not advisable, or may require a lot of work on your end:
– Fix it yourself or hire someone to modify that broken item. (never update again).
– Replace your usage of that theme/plugin, which isn’t always easy.
– Toggle the other item off & on when you need to edit menus, as it only affects the admin menu editor.
Lastly, this isn’t gonna affect just our plugin, there are dozens of plugins that do it the same way we do, so those wouldn’t work with your setup currently either.
Hope that helps.
