/wp-admin is white page

Hello everyone. I am using the7.io license to create my own website. Website works normally but often spam posts. And recently my /wp-admin page is a blank page. I have consulted a lot on Google support. But still not fix the problem. I can’t figure out where my problem is. I look forward to your help.

Hello, I think it is because of the some issue in the code. Add additional information right now it is hard to tell what is the problem.
