MyBB Community Forums

Hey, need some help here. This error shows up everytime a user sends a Private Message, use the "Search" option and tries to search all the users posts.

Since i bought some forums from the previous administrator and transfer them to my VPS, they are really really slow. Sometimes it takes 40 seconds to refresh the index page. I think it has something to do with the database because normally when i check the debug of the forum, the DB Processing Time is something like 40 seconds (90.54%). I ask someone from the VPS and they say that the forums are slow because of some kind of external source (orange.cumulus-cloud.com).
www.dragonball-pt.com
www.naruto-pt.com
www.pokeforum-pt.com
www.videogamer-pt.com

Whatever was running on ""cumulus-cloud.com", it seems to be gone. That might be why it's so slow. Maybe it was used like Cloudflare, as an anti-ddos measure.

A lot of your forums are over 100k posts, you should join the "Big Board Owner" group:
http://community.mybb.com/usercp.php?action=usergroups

We have a dedicated sections to help optimize big boards.

I solved the pm problem with the help of Pirata Nervo. The search option and the user`s posts searching need to be fix.

They're nearly all 300k+ posts, huge databases, that's why I mentioned you should join the BBO group and seek optimization help from the BBO section.

There's information on converting your database to InnoDB and even using Sphinx to help maximize performance.
