My MT Activity Logs were FULL of plugin errors pointing to Blacklist, BookQueueToo, Blogroll, and QuickLinks. (essentially, any plugins that are in their own dedicated directories inside mt/plugins) These plugins have always worked without fail from the front end, so I was mystified at the copious error messages suggesting they could not be found.
Here is just one sample of a variety of similar messages:
Plugin error: /home/user/domains/domain.net/public_html/mt/plugins/Blacklist/Blacklist.pl Can't locate Blacklist/Plugin.pm in @INC (@INC contains: plugins/Blacklist/lib ./plugins/BookQueueToo/lib /home/user/domains/domain.net/public_html/mt/
Searching the MT Support Forums and google pointed me to a very simple solution. In each plugins .pl file I edited the "use lib" line to include the full path per the following example:
use lib /home/user/domains/domain.net/public_html/mt/plugins/PluginName/lib
Voila! No more error messages. :)
