Error upgrading to 2.1 beta 2 from 2.0.11

[Talltree]

Followed the instruction for the Large Upgrade when I try to run "upgrade.php" I get the following error:

BLOB/TEXT column 'txt' can't have a default value

I'm certain its something simple but it has me stumped.  Help appreciated!

why are you upgrading to SMF 2.1? it is in beta for a reason. also you should be using the files on github.

As Illori said, please don't do the upgrade on your production forum. If it's a test site then please do so (using the latest files from GH) and report your results

Please post the complete error you get. A printscreen works fine too
