WordPress 5.5 Compatibility

I updated to WordPress 5.5, and my Posts Slider started displaying the incorrect categories on resave. I noticed when I opened the slider there were no categories checked and all the options in the right column have some visual anomalies but function.

I am using the most recent version of the plugin.

    I'm unable to reproduce the issue on my side - categories and other taxonomies seem to display correctly, and there are no styling issues in option sidebar.

    Are you 100% sure that you're using the latest version of the plugin? You can take a look on Plugins page (3.4.0 is the current one).

    Also, possibly, some other plugin or theme is causing the styling problem after an update. Try to temporarily deactivate other plugins.

    I also have the same issue after upgrading to WP. Cannot access general options just like screenshot above. Any update on the issue?

    @guidotramontano, can you please open a separate private discussion and provide temporary admin access?

    @manieroo, the fix for visual UI issue in admin area was already released https://dimsemenov.com/plugins/royal-slider/wp-update

    If you're having some issues even after the update - most likely one of your other plugins or theme itself has an error that blocks execution. There was jQuery update in WP 5.5 which broke many old plugins, this can help with it https://wordpress.org/plugins/enable-jquery-migrate-helper/
