40
for me, the modules that do not worl are wfdownloads, xooperstore and xcgallery. not sure about xoopsgallery.
just bypass the module by adding a line like system bypass.
around line 40 of simpified_url.php
&& ( !preg_match("/\/modules\/system\//", $_SERVER['SCRIPT_NAME']) )
&& ( !preg_match("/\/modules\/xcgal\//", $_SERVER['SCRIPT_NAME']) )
in the example above(bold)i added bypass for xcgal
