1. Which plugin is this?
I'd need to check which method or function it hooks, to append that additional information.
Also, please check your plugin’s "metadata.json" file.
Look for the "load_order" option, it defines when the plugin is loaded in Q2A.
I can't remember for sure, but options like "before_db_init" or "after_db_init" might also affect the layer override priority (for example, whether the theme or the plugin loads first).
2. About the hidden profile privacy:
The Polaris theme has its own custom User Profile sections, so you’ll need to wrap those sections with your plugin’s option.
Here’s an example:
if (qa_opt('hide_user_profile')) {
// Custom User Profile section from the theme goes here
}
