I had to move up from 2.2.4 today because our hosting service no longer permits use of php 5.2, and OJS 2.2.4 won't run in php 5.4.
I tried the 2.2.4 to 2.4.2 patch file but that resulted in many "Hunk" errors and REJ files. Could not locate a way to determine how to resolve this problem in the forum.
Also tried installing 2.4.2 package via that set of instructions.
Currently the site does not locate the issues of the journal. And the OJS version in the "about" page has not been updated. (I know that this means that the upgrade did not complete correctly, but am not sure how to locate and resolve the error.)
Per one forum suggestion, I set the "install" to off in config and tried installing that way; immediate DB error was Table not found: "copyed_assignment". and the install aborted.
I've reset the install and set the debug to on; am not seeing any obvious errors (www.ams-net.org/ojs/index.php/JMHP
) I'd really be grateful for assistance! Thanks in advance.
