Ahhh... Another case of incorrect installation (file placement)...

There is no file on the store side that is expected to call the init_includes folder. Meaning the incorrect includes/auto_loaders/ file is placed in the store/catalog side... config.user_tracking_install.php should not be in the catalog directory it should only be in the admin directory.

All files and folders in YOUR_ADMIN directory should be placed only in the directory that is your secret admin. All files in the base includes directory should be in the catalog's includes directory. None of the files/folders found in the YOUR_ADMIN directory should be copied to the store's directory.

Guess I'll have to do with this installer like I did with another plugin which is to prevent operation of the auto_loader when installed into the catalog side, generate a message or delete the file, etc... to prevent the issue that is being seen.
