Hello, I have started web hosting reseller business and I am using the medium reseller plan of reseller by Zain Hosting, today I have noticed a problem from a client that he cant access his account after logout, so I have checked and investigated the issue, the problem is
WHMCS Error for all Users – Login Details Incorrect, Please try again. All my clients and users see this message when they try to login their client area of WHMCS.
I am conforming that the they have use accurate passwords and email address / user names, and I also try to solve the issue through lost password option but not succeeded.
check your WHMCS health area section, maybe you will get a clue about the issue.
go to your health section of your whmcs
Help > System Health Status
and check is the MYSQL strict mode enabled?
Hello I have checked in health status
MYSQL strict mode is not enabled, but I have seen some SSL warnings and issues.
Okay I have Understood your issue.
you have redirected your urls to https SSL through htaccess file, just remove the SSL redirects to https and go to
WHMCS Admin > General Settings > General and change put the HTTPS value in the WHMCS System URL and Domain fields.
