Hi all,
here is my backend link: https://www.cynthia.byethost6.com/wp-admin/cynthia680808
and I found I couldnt log in after I upgrade wordpress to 5.6 Chinese version and here I attached the screenshot of erro page.
there doesn't show anything to show any error php file, just show I have a critical problem on website? I don't know how to fix it.
I could see my frontend is still working : cynthia.byethost6.com
however if i can't log in the backend , it's impossible for me to update my articles and photos on this website...
Is there any professionalist to let me know how to fix this delimma? I am getting crazy ...
