Updated the board from 3.1.9 but whilst some areas worked I started getting crashes/error messages. I was able to disable all extensions but the board continued to crash.

Clear cache/production folder and remove that auto backup extension, seems it doesn't work with 3.2.x. Try this one Auto db Backup

[Heuerman]

Just cleared the cache, deleted the pico autobackup from within the php database but the error message is still there on accessing the board.

[GanstaZ]

Did you clear the cache/production folder using ftp?

[Heuerman]

Yes, deleted all the contents of the cache folder.
