Classifieds and Directory Clashing with Search and Filter Pro

Hi,

I was recommended through another ticket to use Search and Filter Pro as a plugin that improves the overall search on a site. I recently found the update/publish button of this plugin is not working on my installation.

After some extensive de-bugging I found the search plugin stops allowing me to save in the admin interface of WP when I have either classifieds or directory activated. Has anyone else reported this? I know it maybe a long shot but would you have any idea what the issue is?

Many thanks
