is_dir() error open_basedir restriction

If you are on Plesk, check this =>

I had this issue as well. It’s making an absolute mess of the PHP error logs.

The issue is that the 2nd parameter passed to path_join is an absolute value and so the path is never actually being joined onto WP_CONTENT_DIR. Calling is_dir on the absolute path: “/plugin-templates/login-with-ajax” is resulting in the warning because on many hosting providers that path will be outside of the webroot.

Current code on line 693: $wp_content_folder = path_join( WP_CONTENT_DIR , "/plugin-templates/login-with-ajax/");

Should be: $wp_content_folder = path_join( WP_CONTENT_DIR , "plugin-templates/login-with-ajax/");

The only change is removing the leading slash in the 2nd parameter.

I fixed this manually on our site, but would love to see this included in a patch version so a plugin update won’t clobber our logs again.

I can confirm @patrelentlesstechnologycom ‘s assessment of the problem: adding an initial slash to /plugin-templates/login-with-ajax/ has the effect that the path_join function sees it as an absolute path.

Since the WP constant does not include a trailing slash, you would want to use an initial slash if directly joining the WP constant and the trailing portion of the path, like this:

$wp_content_folder = WP_CONTENT_DIR . "/plugin-templates/login-with-ajax/";

However, if using the path_join function, the initial slash must NOT be present:

$wp_content_folder = path_join( WP_CONTENT_DIR , "plugin-templates/login-with-ajax/");

I also applied a manual fix to avoid errors popping up. Please fix!

I can confirm that this bug is still relevant, please check the proposed solutions!
