Hello,
Thank you for your reply. What do you mean by "your template was not completely ready"? Everything was completely updated, I had only installed the Helix update at the end.
Out of sheer frustration, I have now unfortunately rebuilt the site with an update from October 28. Out of carelessness I had deleted the last backup. Now I have to work a lot again to finish my last work.
best regards
Torte
The other problem is that I have no response to my question about the "Unhandled Runtime Error TypeError" issue. It seems to me that not all updates are ready for online mode. Too many problems lately, are the proof of that.
