Thanks for checking in @aapc . Again, this doesn’t bother me at all, as I see no performance issues other than the messages when debug is on. But unfortunately, after updating all plugins on the test site, still showing the following:

Notice: Function _load_textdomain_just_in_time was called incorrectly. Translation loading for the the-events-calendar domain was triggered too early. This is usually an indicator for some code in the plugin or theme running too early. Translations should be loaded at the init action or later. Please see Debugging in WordPress for more information.

I stripped my site down to just the default theme, and only activated the two plugins. Tested with 8.2 and 8.4. Not sure what else to do. I just turn off debug, so it doesn’t really bother me as I haven’t noticed any performance issue. Here’s my thread from TEC:

Ok, thank you for reviewing this!

It simply shows in the wordpress backend when I turn on debug. The messages only come up when I activate events calendar (after deactivating all plugins). The message I shared is the only one that mentions event calendar, but there are also other messages, here is the full list:

Hi Alex, thank you very much for your response and initial investigation. I think the issue is related to the use of “Patterns” in WordPress blocks. When the gallery was within a synced pattern, it would not work. When the block was detached from the pattern, the gallery works again.
