Hoping someone has a solution to an upgrade problem.
Prior to upgrading OJS, we upgraded PHP to 7.4 on our CentOS 7 server. After upgrading OJS from 2.4.8 to 3.2.0-3 using the tar file, we get an error message after logging in as a Journal Manager:
“An unexpected error has occurred. Please reload the page and try again.”
The URL showing in the browser location field is:
https://journal.ourschool.edu/index.php/journal/submissions
If we click OK in the error message window, the error message goes away and we have access to the Submissions screen.
A “Loading” message appears at the top of the screen with a circular spinning graphic that continues until we browse away. A list of links appears on the left side of the page: Submissions, Issues, Settings, Users & Roles, Tools, and Statistics. None of the links works, except the Submissions link reloads the page.
The message in the php error log says:
