The problem is that in the globals/globals.php file I have it set up to use the file permissions for the folders and the folder permissions for the files.
The solution is to update that in the globals.php file. I'll try to get an official update out early next week to resolve this and any other issues that pop up.
To fix this. go to /webassist/globals/globals.php and update lines 54-55 from:
$GLOBALS['permissions']['dir'] = base_convert($GLOBALS['WAGLOBAL_File_Permissions'],8,10);
$GLOBALS['permissions']['file'] = base_convert($GLOBALS['WAGLOBAL_Folder_Permissions'],8,10);
to:
$GLOBALS['permissions']['dir'] = base_convert($GLOBALS['WAGLOBAL_Folder_Permissions'],8,10);
$GLOBALS['permissions']['file'] = base_convert($GLOBALS['WAGLOBAL_File_Permissions'],8,10);
You will probably also have to delete the folder: /webassist/plugins/catalog/scripts/image_cache
Since it likely has folders with the wrong permissions already that will be recreated correctly now that the globals file was updated.
