Hello,
We are using 2.4.8.0 version of OJS. In order to update to 2.4.8.1, I install files and the database that are backed up at a different folder (I do in this way because the journal needs to work regularly.). When I activate, the menus located in the left side disappear and the link “site administrator” does not work. When I click, a blank page appears. Can I learn the reason for this?
