We have OJS 22.214.171.124, I am testing upgrading it to OJS 126.96.36.199. I used a backup from the production server (files and database) and installed it in a local server. At the begaining the upgrad failed. I learned from the fourm that I need to convert all InooDB tables to MyISAM and also change the default database engine to MyISAM.
With these settings, the update completed successfully but the theme looks corrupted.
The frontend is almost the same with one exception that the font is not italic anymore. While the backend shows many problems. The left hand menu in the dashboard page looks scattered and not showing at all in the “Administration” page (as in the image at the end).
I installed “Classic Theme” and “Manuscript (Default child theme)” but nothing change.
Any suggestions is appreciated.
