Showing Blank Page

Hi

I am facing an issue with word press posts.

Existing behavior : when I click on posts–>all posts–> edit.php is showing blank page instead of showing list of posts. of-course it was working fine some times If I DE-activate all the plugins. If the plugins were activated it doesn’t work.

Desired behavior : I want to see all the posts even after Plugins are activated

I am using this template :
Rolas Sepuluh

can anyone please help me to resolve my issue asap ?

Immediate response is highly appreciated
