Issue Upgrading from v3.0.20 to v3.1.x

[sheddingmyskin]

I am currently attempting to use the update feature within Formtools and getting the below error:

I updated all of my modules to confirm that they were not causing the issue.

When forging ahead, by click upgrade anyway, I get an error about the server being too busy and it rechecks every 30 seconds.

Sorry @sheddingmyskin, I'll update the site this weekend to eliminate that upgrade script altogether. It hasn't been working for a long time. I'm afraid upgrades have to be manual. See instructions here:
