Warning: mkdir() Error

The error is telling you that the webserver doesn’t have permission to write or create new files / directories, which are needed for storing the cache files.

You either need to chmod the wp-content/uploads directory or ask your hosting provider to do it for you.

I have the same problem, but it worked before the last update.

The problem is on the last line :

# critical path file
$currenturl = fvm_get_protocol($_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"]);
$file = sanitize_title($currenturl);
$save = get_stylesheet_directory().'/criticalcss/css/'.$file.'.css';
$generate_gulp_path = rtrim(trim($generate_gulp_path), '/');
if(!is_dir($generate_gulp_path.'/out')) { mkdir($generate_gulp_path.'/out'); }

I’m trying to see if it’s a permission problem ^^’ !

There was a bug with 2.1.8, please update to 2.1.9 and it should be gone.

I checked my permission and it’s ok for the upload directory. It seems to create files somewhere else, I don’t really know where (in the wp-content theme directory ?).

No, that is a hidden development version and it would try to create it based on a database value.

This will eventually be released, but for now it’s fixed, just update.

Oh yeah ! I didn’t see your answer… I’m trying again, clean my log and I will tell you ^^ !

It’s perfect with 2.1.9, no error message anymore ?? You can pin the topic if you want ^^ ! Thank you and see u later ?? ! Have a nice day ?? !

Yeah, error is gone after update. Thank you.
