I'am getting blank page after intallation OJS (for all versions)

I have installeded different version of OJS (such as 3.3.08, 3.1.1.4). After the installation page it takes me to the login page. When I click on Login, it takes me blank page. (Http error 500).
url link is like that …/index.php/index/admin/contexts
I have tried that on localhost and host
Please help.

Hi @A_B,

For errors such as these it’s best to have a look at the PHP error log and report on errors from there - could you do that please?
