I’m not sure what that is, but as these warnings are coming straight from the low-level PHP code, my guess is that the fix will have to come from changes to the plugin’s PHP code, for example like this: https://stackoverflow.com/a/2471692/1163042
Thanks Ramona! I send you more information via your support page.
Yes, I’m using Accordion Menu 9.3.10 and I’m seeing these messages in the PHP error_log that I’ve enabled using WP_DEBUG and WP_DEBUG_LOG (https://ww.wp.xz.cn/support/article/debugging-in-wordpress/#wp_debug_log).
I am having the same issue: it’s no longer possible to have a menu visible to more than one role simultaneously.
