Description of the problem I’m having.
When I try to publish a new issue, I get an error which says “Failed Ajax request or invalid JSON returned.” The content of the Ajax response seems OK, but the server sends it with a HTTP 500 error.
PHP’s error log doesn’t show anything new and, unfortunately, my web hosting provider does not allow me to see Apache’s error log nor provides any assistance with this.
Steps I took leading up to the issue:
Go to Future Issues → Click on the arrow next to the issue I want to publish → Click on “Publish Issue”
What I tried to resolve the issue:
Based on this other thread, I tried deleting the issue and creating a new one. But the error persists.
Application Version - e.g., OJS 3.1.2: OJS 188.8.131.52
