CustomLocaleAction.inc.php on line 28

Hello,

I’m seeing a few lines in my PHP error log from this kind:

This is happening for a while and i was hoping it will be fixed in time, but i still see the error. Also there are some lines with this message:

[12-Jan-2023 17:02:24 Europe/Ljubljana] ojs2: 404 Not Found
[12-Jan-2023 17:03:28 Europe/Ljubljana] ojs2: 404 Not Found

I only check the logs only when we face a problem with our journal, so we published 2-3 articles in the past 1-2 months and there was a problem automatically registering the DOI to CrossRef and problems with the metrics, downloads and views… they where slow or the numbers were 0 for 2-3 days.
How can i run/force the scheduled tasks to be finished and renew the statistics?

Additional:
We already have CrossRef XML Export Plugin setup and the DOI Plugin Settings also. Doing a manual deposit on the articles is working, the articles get the DOI registered immediately.

Update edit:
I saw this in the site settings menu, I don’t know if this is a problem.

Our OJS version is 3.3.0.11
PHP version 7.4.33

I can provide more information if needed.

Best regards,
JHRS
