After upgrading our website ephjournal.org/eph from OJS 3.1.2 to OJS 3.1.2.1, I am facing issue on loading the page Setting–> Website–> Appearance TAB. It only shows a blank page and other tabs are working fine.

I have upgraded from OJS 3.1.1-4 to 3.1.2-1. The website is working good. All pages are loading properly EXCEPT settings–>Journal.

Gives the error message " DB Error: MySQL server has gone away"
