Wizzard shows blank site

Hello … i want to update with update wizzard.
after clicking i get only blank site … ( white one )

what can be wrong ?

regards
Michael

No one any idea ?

since I was installing from scratch because Im starting with SuiteCRM atm, I just installed again the whole package instead of updating. But (the reason) I was recieving an “Internal Server error 500” or something like that after the first “Next” and I read something about file permission. Are your file permissions correct?
