can't access Admin Panel of opencart

I have a subdomain and i uploaded opencart 3.0.2.0. After that i installed it correctly. Now on checking my store front is working properly, but i cant access the admin panel. Whenever i try to access, it is redirected to the admin login page again. i think this is a problem with infinity free, because i used to check the same script installed in another site of mine(not with infinity free), it works perfect. please help me.

then, i tried to install opencart via softaculous and it gave me an error.

Opencart is not installed as far as I can see. During the installation wizard you can choose your admin credentials and you can sign in with those credentials after the setup has been completed.

I don’t know of any reason why you wouldn’t be able to use those scripts here and I’m not aware of any problems with it.

It gave you “an error”? What error? There are thousands of different errors you could see on Softaculous, including the exact error would help a lot.
