Roundcube Version 1.5.2

Hi,
Without further knowing much details of the roundcube inner workings, this looks like a namespace issue.

Call to undefined method rcmail::build_folder_tree

...is a static function call to the class named rcmail, which does exist in #4: rcmail->action_handler, otherwise the steps before that could have never taken place. (EDIT: PHP stack traces are actually backwards, because #5 is the entry point and #0 is the last point run that triggered the error.)

In other words: advanced_search apparently has a namespace _whatever_ line somewhere, which breaks structural reworking that were introduced in Roundcube 1.5 (or even earlier).

Is this a built-in plugin? I doubt that, others would have this issue and you wouldn't wait here for an answer. Where did you get the plugin? When was it last updated? Could you post a link?

Oh my. Please forget my previous request for the link. Captain Obvious just said hello. How did I end up here? 🤔

I hope plugin author read this thread and help us )
