Thank you for your answer.
I tried 3.16, 3.17, 318 and 319.
I tried php 7.3, 7.4 and 8 versions.
WP version 6.0
Theme Regn Version: 1.0.5
Codeless Framework
Version 1.0.1
I get the error "codeless_custom_panel_php on line 11"
I tried all of them. some are working. works before. When I turned it back on after 10 or 15 hours, I got different errors (different version, different error output).
I will be waiting for your reply. Thanks again.
