the_content

whenever I try to create a new loop I get this message.

“Sorry, the content area was not found in your page. You must call the_content function in the current template, in order for Elementor to work on this page.”

I can create templates with everything in elementor with no issues. Only when I use ele Custom skin loops this happens.

I have tried with :
Hello elementor
Astra
Oceanwp
and skelementor.

I have tried disabling all plugins.
