Error trying to save GENERAL SETTINGS

I finally upgraded AG2.2 to AG2.3.1 and then AG2.3.4.

Everything looks working but when I try to save the configuration it returns:

MySQL Error : Query Error
Error Number: 1054 Unknown column 'thumbnail' in 'field list'

Can u help ?

Hi, bob

Yes you will need to run my upgrade script to update the database. www.carbonize.co.uk/update.zip I think

It returns error 404...

Yeah my mistake - http://www.carbonize.co.uk/AG/

Everything looks to work fine now!

I've done a little DONATION for you: not enough for a Ferrari yet... !

Ciao Bob

Every donation is gratefully received. Personally I don't like Ferraris though, would prefer a nice Lexus.
