Error upgrading to 1.7.5

When the database is upgrading from 90 to 91 I get this:

An error occurred running the upgrade. Please take a screen shot of this page and seek help. Statement number: 91. Error Message = [SQLSTATE[HY000]: General error: 1034 Incorrect key file for table ‘log’; try to repair it]. File = [Array]. SQL = ALTER TABLE log ENGINE=InnoDB].

Any ideas?


Sounds like you have corruption in your MySQL database files. Googling that error also suggests in a lot of cases it’s where your server’s hard drive is full.

Perhaps you’ve not been running the maintenance script regularly and so months of accumulated logs have filled the server up?
