Hi.

Works, I can confirm.

1. Check if Helix plugin is published !
2. You can try Helix Ultimate 2.0.9 - in case of.
3. What does it mean "unstable" ? More details, maybe share link to short video.

Pro = Professional, not Personal.

Here is screenshot from Forum User real "hospital" website , all works - no magic tricks. Joomla 415+SPPB 387+HU 2010

Thank you for your quick response. No Helix plugin. That didn't work with Joomla 3 either. I attach the video, can't save the completed page, I don't really understand the Helix plugin connection. https://youtu.be/gW0A5OY1Umc

Indeed - Template - no relation, I mentioned becuase many users have it.

On your video you you added 3 addons: Numbers, Icon and Image - and they worked.

Sorry but what is wrong?

Do you have enabled Joomla cache? If yes, disable for time of edition.

The problem is that it says on the screen that it is saved, but you can't close the page edit. Close doesn't work, if I leave the page I don't have this page, there is nothing in the page list. Disable Joomla cache.

In general it should work.

Can you share access ?

BTW

In next 24h should be SPPB 4.0 - one step ahead

Send login data. Thanks for the tip about SPPB version 4.0.

Do you have Firewall installed on your server?

something is blocking JS requests.
