UBB.threads PHP Forum Software Community Forums UBB.threads 7 Installation and Upgrade Support t my include directory

While upgrading from UBB.threads 7.2.2 to the latest version, install/upgrade.php script gives this error:
"Fatal error: Call to undefined function: upgrade_header()"

but my includes directory is the same as day ago,

and in phpmyadmin I was found that some tables have't some columns. please help quickly (without reinstalling)

Hmm, that's very strange. The upgrade_header() function is part of the upgrade.php script, as long as your running the most recent one.

Are you sure everything in the install is from 7.3, nothing old?

What version of PHP are you using?

it's ok problem was in base_url. for installation or upgrade is nessesery but for using is not
