Did the latest updates to my Ubuntu 9.04 machine and restarted. Went to my Koha Opac and got the maintenance page That was odd so I checked and MySQL wasn't running. Went to start it manually sudo mysql start and got this: ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) hmmm... Thought about it for a moment and decided that maybe I should try mysqld That worked but I got this 090818 8:41:40 [ERROR] mysqld: Incorrect information in file: './koha/ systempreferences.frm' Now, here are the last things I did that would have effected mysql. Yesterday I was playing with adding Owen's tables for the new items php. I have also been playing with the CSS for the Opac, header, credits, navigation, etc.. as I work on trying to merge the library webpage with the Opac. Any thoughts? Do I just need to restore my koha database?
