Hello Leroy,
I hope you are doing well.
Till now, our templates are not compatible with Joomla 3.10 or Joomla 4. As you have already updated to Joomla 3.10, you have to install Helix Ultimate 2.x.x and then only it will work fine. However, we highly recommend not to update to Joomla 4 now if you are using templates as they are not compatible yet.
Our dev-team is working on it. Those will be compatible within a few days hopefully.
Not to mention, please have a backup of your site before changing or updating anything.
I hope you got the solution.
Thanks!
