I tried with localhost, I tried to live it blank, I tried with my server name,I tried other diferrent name combination. No way, I cannot login, I ALWAYS get a 400error.
jpdemi, I modified the home_url according to yours and now I dont get a 404 error anymore. I GET THIS : LOGIN FAILED, PLEASE ENTER AN OTHER LOCALHOST,USERNAME AND PASSWORD.
I found a solution/workaround! Indeed, it is impossible to login via the normal login panel. I guess it is because we are only hosted, we are not owner of the server, therefore we do not have "root" access to create new databases!
But, the script has the possibility to "direct_connect"!!
And that's the only way for me to get in! I filled out the corresponding fields in "mysql.cfg" and now it works fine!!!
A great help, this script!!! :-)
Your hint, Aford, led me to the solution. Thanks again!
