Hoi Chris,

Disable CSS and JS compression in Template Options, then clear Joomla cache and check again.

Done that still same issue

please share access to admin area

Check below

Can I be Super User?

Role changed

No idea, I tried almost everything.

Can you recover site from backup - from date where was OK?

And update only SPPB. Then we will think again.

Raw Helix Ultimate works fine.

Yes, I can.

So recover, update SPPB and test, in case of problems ping me later. But do not update Helix plugin. It may be a source of problem.

But still doesnt work fine with Raw Helix Ultimate. The hamburger icon stays visible even in desktop mode.

Restored to latest working update. Updated SP Pro. All looks good now. I didnt update the helix plugin to 2.0.10

So we still working with helix plugin 2.0.9

Thanks for replying.
