As the complexity of a MODx site increases, degugging can become very difficult.
Messages can lead the developer to investigate the code at the wrong location.
The purpose of this thread is to list common errors and possible causes.
It is especially dedicated to MODx snippet and plugin developers.
This thread comes as complement of
http://wiki.modxcms.com/index.php/Common_snippet_error_messages_and_their_meaning and should be easier to edit by everyone.
Posting rules
- Post only after you found the solution to the bug.
- Be brief.
- Avoid snippet-specific errors; try to list general errors and possible cause(s).
