Journal manager cannot change journal setup

Hello,
I am enrolled as a journal manager and using OJS 2.4.6. everything was fine until yesterday I found that I cannot change journal setup from my account. I tried to modify the custom block plugins (remove some of them and add new ones) and clicked save & continue, but nothing changed. the blocks I tried to remove were still there and the new ones didn’t appear.
The error also occurred when I rearranged the side bar blocks. after I moved some blocks and saved it, nothing happened. then I tried to change the theme, but again, it’s not working at all. there’s no warning sign or whatsoever.
I’ve tried so many times, even with my fellow journal manager account.

Any inputs/ideas are greatly appreciated. Thank you.

Hi @zuperhornets,

Did you check your site’s error log?
