Error: SAFE MODE Restriction @ cloudfront

Using a shortcode for JW Player integrated with Amazon S3 and Cloudfront, I get the following error message:

Warning: realpath() [function.realpath]: SAFE MODE Restriction in effect. The script whose uid is 42454 is not allowed to access /tmp owned by uid 0 in /var/www/sangkufferten.dk/public_html/wp-content/plugins/s2member/includes/classes/utils-dirs.inc.php on line 200

However, the audio file streams ok.

I contacted my host, and was told it “is probably something in the S2member setup”, so I hope you can help me.

Best regards,

Karina

Thank you for reporting this important issue.

I just took a look at what exactly safe mode is. This is a PHP INI value that affects all connections through WordPress. It can prevent some requests through WordPress’s HTTP class to fail, which is probably what’s causing your issue.

You’ll have to turn off safe mode to get this to work. This is a PHP.ini setting, so if you can edit that file you should see where it’s set. This feature is consisdered problematic, which is why it was removed in the most recent versions of PHP.
