In all my years with SMF I have never seen this. What does this mean:
SQLite3::exec(): database is locked
Found it in my error log this morning.
Means you're using 2.1 with SQLite 3 for caching and two things tried to write at the same time.
Oh ok. Not as bad as I thought then, lol. I thought someone was tryin to do something not so nice for a bit there. Thanks for explainin. :)
