Yes, I did install support manager pro and it did conflict with support manger. I have since uninstalled support manager pro but had issues with removal as well. Even though it has been uninstalled, the menu still exists but shows mysql error when clicked. Not sure if that is related or not.
I did discover some mail issues(phpmailparse) with the server when I investigated, but after running the cron manually the error still exists. I'll try removing the log from the dbase next.
