Can't save page because of error

[Lyubov Alekseyeva]

Good evening!

I can't save page in Confluence OnDemand after adding tabel rows, text or attachments. It happens in only one space, in others everything's ok.

This message appears when I try to save the space:

"Your request could not be processed because a required security token was not present in the request. You may need to re-submit the form or reload the page."

Please help me fix it.

Thank you.

The problem was solved by:

Removed the problematic lines from the dabase indicates I am not 4.3.5, and tried to upgrade again to 5.1.2, and it magcially works.

It seems that your database is on version 5.1.1 but the dbconfig file is still using 4.3.5, that might be the problem, can you please double check whether you've download the correct installation kit for Confluence 5.1.2?
