The current version of OJS we are using is 3.3.0-10. Yesterday, we found that the “Journal”, “Website” and “Administration” columns in the “Settings” section of the background couldn’t be opened after being clicked. After looking into the problem, it is likely that the versions of some plugins are incompatible. Can I directly upgrade to version 3.4 now? What issues should I pay attention to? Is there any specific upgrade documentation available?
