Error on Helpdesk since last update

Hello,

since yesterday morning no articles are displayed in the helpcenter. Only the categories appear and after clicking on them a login page appears. However, access is enabled for everyone. Sometimes also a note appears that the page does not exist. No changes were made and all articles, categories etc. are of course released.

Is it me? Or is there a technical problem?

The address of the helpcenter is https://kwmanagement.zohodesk.eu/portal/de/kb

Greetings

Thomas Rapp
