The following error may appear in your Theme Options Update page

Warning: file_get_contents( [function.file-get-contents]: failed to open stream. … on line 19

This is due to restrictions set by your web host.


The Solution

If you have access to your server’s PHP configuration, find the following key in your php.ini:

allow_url_fopen = Off

Change the value to “On”. You should now have:

allow_url_fopen = On

If you can’t edit your php.ini, you may email the error to your web host support and ask if they can enable this option in your PHP configuration.

Most hosts are willing to do this, but if you have shared hosting where this cannot be set, you will need to Update your theme manually.
