vb 4.2.5 Upgrade error

The upgrade hangs even if I refresh the page.

I already searched and tried the different solutions but nothing worked.

I cant also login to the forum and adminCP. After the interstitial page "Thank you for logging in....", it just return to the previous page and didnt log in..
