When you post code in this forum, you should only post the working code needed to get the point across. Extraneous code just confuses the issue.
Also of note, if you only have a single file for your plugin, it makes no sense to create another subdirectory to contain that one file. You should only create a subdirectory if you have 2 or more files for your plugin. If you just have one, place it in the .\configs directory itself.
