CB

If your site is contained in a folder prefixed with 001 (e.g. 001_test) this will cause the autoloader REGEXP to treat the \0 as part of the replace syntax.

AutoLoader::registerExactMap( '%^CB/Plugin/AutoActions/(.+)%i', __DIR__ . '/library/$1.php' );

This would produce the following pathing issues.

ROOT\wwwCB/Plugin/AutoActions/Trigger/AdminTrigger1_test\components\com_comprofiler\plugin\user\plug_cbautoactions/library/Trigger/AdminTrigger.ph

Due to the below replace syntax.

ROOT\www\001_test\components\com_comprofiler\plugin\user\plug_cbautoactions/library/$1.php
