Fix for uninitialized $FILTER_APP variable in functions.php
Hello, sorry for the lack of support in this forum. It's always best to use the squirrelmail-plugins mailing list for support requests (although we will continue to watch for bug reports on this tracker from time to time).
As for your specific issue, it should be solved in the newest version of this plugin (2.0), which is in beta testing at the time of this writing and available for download at the project web site.
If you have the interest, we'd love to hear whether or not you are able to build the Server Settings Backend plugin's SUID backend on your system.
