Error upgrading from 5.0.1
 

Just found a cracking bug.

When upgrading a 5.0.1 gallery to 5.62, in upgrade.php it calls 'upgradecategories' in php-inc.php

Problem is, the query used in upgradecategories refers to the 'subalbum' field in the categories table.

... this field isn't added until 5.2

doh!

I presume if I just add the field via SQL and proceed with the upgrades it will sort itself out anyway?

Just back out to main upgrade screen and run the next upgrade making sure to run 5.0 through the last 5.6 upgrades all once and you will be fine
