what should I do if the plugin I use doesn’t work when I click settingsERROR

Hi @R1Z4L, can you please check what you are getting inside your php_error.log file? You can visit this link if you are not sure where to find it.

I have already checked the php version and error_log file. But I didn’t find the mistake. Please help me sir

Hi @R1Z4L, what specific version of OJS 3 you are using? Also do you see any error in your browser’s developer console?
