cannot login on whmcs admin panel.

[kazurengan]

hello, i've been trying to login on my whmcs admin panel, I contacted my host and they said

the problem is not on their side, i even tried to clean cache

and re install WHMCS. but nothing worked.

when i enter my login details i simply get back to login area again, like a page refresh.

and i'm sure my login details are correct since i tried with other password and gave an error.

but doesn't show any error when i enter my login details correctly, just a simple refresh happens.

 

How could i fix this problem please?

is it possible to login as client, or different admin user?

 

check WHMCS system requirements too

make sure that MySQL Strict Mode is disabled, then try to login again?
