[Theme Check] need to fix these errors?

Necessary to correct errors identified by the Theme Check caused by Redux Framework?


WARNING: file_put_contents was found in the file includes/redux-framework/ReduxCore/inc/scssphp/scss.inc.php File operations should use the WP_Filesystem methods instead of direct PHP filesystem calls.

Line 4475: file_put_contents($out, $css);
Line 4476: file_put_contents($this->importsCacheName($out),

Generally the WARNINGs are OK for reviewers. Have you edited the core files? If not, it should be definetely no problem.

Okay, not edited files, only options.php

Thank you!
