CMS Made Simple Forums

Hi all, I updated a website from version 1.11.13 -> 1.12.2 -> 2.1 -> 2.2.8

After this last step from 2.1 to 2.2.8 some backend links don't work anymore.

Examples:
Content > Content Manager > "Delete this page" icon is clickable but does nothing.
Content > News > "Delete article" icon is clickable but does nothing.
User Management > Backend Users > "Delete user account" icon is clickable but does nothing.
Site Admin > Module Manager > Upgrade is clickable but does nothing
Site Admin > Module Manager > Remove is clickable but does nothing

Does anybody have an idea what I can do to fix this?

Try clearing your browser cache or using incognito mode.

Yes DIGI I am now on a different computer and everything works fine! Probably some conflicting caching indeed.
