please help

is admin password ok - is it complex enough ?

Turns out the issues were passwords:
no hypen allowed. It must contain numbers, upper and lower case letters.
slashes not allowed: the command must be executed without the slashes
and proper language and currency codes. E.g en_GB
In addition, rewrite and session save also prompt the error as well.

thanks for posting solution !
