Are you using custom templates?
Since you are the only one reporting such a serious issue, my best guess is your `base/head_navbar.tmpl` is custom and thus outdated since the upgrade.
Please re-add your changes to the up-to-date version.
Thank you for the information. I have found the head_navbar.tmpl file within another branch of our repo so I will work on getting that resolved…fingers crossed.
But still, could you please try upgrading to the latest released version instead (1.25.3)?
Maybe that fixes your problem already if you don’t have custom templates.
