Thank's!

It seems Joomla 4 is not compatible with PHP 8.2.0. Drop PHP back to 8.1.x

Thank you, AMurray, Excuse me, If I return the site to 8.1 on the hosting, then the site will not break?

It should be fine on php 8.1

Thank you, gws I changed it. PHP version 8.1.13. Didn't help. "There is no "joomla.treeselectmenu" asset of a "script" type in the registry."

Which module do you want to install?

[AlViKo]

Does not give any..

[AMurray]

per @chmst's question, what module are you trying to install that gives you the error mentioned in your question .

The reason for asking, is that third party extensions may not run on PHP 8.x where Joomla itself (bare bones/default install) will work fine.

Drop PHP to 8.0.x and see if that helps. I would assume your host allows that.

Thanks for the reply, AMurray. I tried to install the Menu module, but when installing other modules from the suggested options, the same error occurred...
Now I will try to downgrade PHP to 8.0...

More Thanks for the reply, AMurray. Indeed, it is possible to make a module on PHP 8.0.
