Dashboards blank after upgrading from 5.2 to 5.4.4

[derousse]

I upgraded Zabbix from 5.2.? to 5.4.4 today and after restarting the server all of my Dashboards are empty.

I tried clearing cookies and cache, but it didn't help.

Also, the Edit dashboard button doesn't do anything, on both existing dashboards and a newly created one.

In the browser console I'm seeing the following:

jsLoader.php?lang=en_GB&ver=5.4.4&showGuiMessaging =1:3843 jQuery.Deferred exception: timeControl is not defined ReferenceError: timeControl is not defined

Please help!

I tried this but the dashboard is still coming up blank.

Nothing was logged to the error_log.

The access_log has:

And the browser console is still showing the same errors as shown in my opening post.

Hi.
Ok so you test other user... Update java 7.4 on Zabbix Server and update browser. Test edge or Firefox...

Thanks for trying to help Sunrise0318. It turns out that we had an issue with a firewall rule which was blocking the web request to load the JS files. This was fixed and it's working fine now.
