Hi there!

I am facing a strange issue since 2 days, one of our Journal Editor(s) is having problem signing in to the OJS site. Whenever, he logs in, 500 Internal Server Error screen popsup. On Investigating the Server Log, I have found some of such lines there:

I have tried clear all type of caches using OJS administration, changed User’s password. But the problem is still there. And surprisingly, it is only happening for that user particularly. Other users are loggin in fine. Please assist accordingly.

PHP 8.x
OJS Version : 3.3.0.17

Hi @Farhan_Abbas ,
I’m assuming that your user is probably Chinese (because of the zh_TW language), maybe you can check the username, first and last name for special characters (not ascii).

This is not the case for this user. This user account belongs to our organizational employee and he is a co worker. I even tried to Log in as this user by using Administrator rights but get the same error. Kindly advise any further steps.

Well, it seems like a very simple way of looking at it, but many of these errors are removed simply by clearing the browser’s cache and cookies.

Hi @Farhan_Abbas,

I think you are missing a user entry for a corresponding review assignment. Try this query:

SELECT ra.review_id, ra.reviewer_id AS user_id FROM review_assignments ra LEFT JOIN users u ON (ra.reviewer_id = u.user_id) WHERE u.user_id IS NULL;

If this provides any results, it means you are missing a user entry with the corresponding user_id.
