I got error "misconfiguration on the server"

dear
I have upgrade my isntalation to verison 6.04.
and now I got error " A misconfiguration on the server caused a hiccup. Check the server logs, fix the problem, then try again."

some issue screens no load . other load without the frame

Somebody could give me any directions or recomendation?

Pièces jointes :

print screens

I’m just guessing here but It shows you’re using default menu manager & theme and it appears the theme is not loading them properly. By any chance, did you move or delete any directories or has the default Dolibarr URL changed after the update?

Check Dolibarr.log which can be found in [code]
dolibarr/documents/[/code

It was SOLVED …
i have updated/changed the permissions of the files ( 0644 ) and folders (0755) and right now it is working well.
Thanks
