Many Problems...
Before </head>
Before </body>
I had something entered there. After the update, both fields are completely empty.
If I fill them in, save them and reload the page completely, the fields are empty again. Consequently, some things on my website no longer work.
There also seem to be problems with the colours. The background colour is simply white, instead of the colour I specified in Helix. The text colours are no longer correct either.
I’ll unfortunately have to restore the backup with the old version
