[SOLVED] After upgrade, FAQ: JavaScript error

[peters]

Hello, we just upgraded from 3.2.8 to 3.3.9, all Packages are on latest versions, FAQ module was also manually reinstalled twice, but we are still getting error, after agent opens Faq -> Explorer:

Core.UI.InitTableHead is not a function

FAQ is on 2.3.2, didn't find any other update...

Thank you for help

Seems to be a Java-Cache-Issue.

Did you restore the whole /var directory?

How do you mean restored from /var.?
I did an upgrade via rpm, running centos 6.5. I didn't restore any files in /var or /opt/otrs, as this should be handled by the upgrade process automatically.
Can the cache be deleted manually?

Hi peters,

1. open a command prompt on the server
2. change the working directory to the bin/ directory of your OTRS installation
3. run the script otrs.LoaderCache.pl -o delete
4. run the script otrs.DeleteCache.pl
5. ensure that var/httpd/htdocs/js/js-cache/ directory is empty

Hi Rooobaaat,

many thanks for pointing to the real cause. After deleting cache it still didn't work, then I realized that we are using custom Theme and I updated it right after OTRS upgrade. But then packages like FAQ and ITSM were updated, which copied new files into the Standard folder, and those files I was missing in our Theme.
After copying missing files, it works correctly.

Did you consider the OTRS admin manual on http://otrs.github.io/doc/manual/admin/ ... hemes.html ?
