Loading Error in Various Sections of Journal Management

Hello,
I need some guidance. Our journal’s website is experiencing a loading error in several sections.

Whenever I click on different sections in the journal’s management panel, the page remains stuck on a loading screen, and the settings for those sections do not appear.

Please advise on how I can resolve this issue.

Best regards,
Ali Akbar
