Many thanks for your response. It’s not explicit on AMP pages. It’s also on other pages: 2023/08/20 10:39:41 [error] 4069776#4069776: *2707034 FastCGI sent in stderr: “PHP message: PHP Warning: file_exists(): open_basedir restriction in effect.

Thank you for the hint that I shouldn’t change the core files, but that’s the only way so far to not show the error in the error.log anymore.
Is there any other way I can solve the problem? Many thanks for your help.
