We are getting this error at the top of our site:
Notice: Undefined variable: http_response_header in /public_html/wp-content/themes/enfold/framework/php/function-set-avia-frontend.php on line 637I’ve already reinstalled twice and disabled plugins, nothing is helping. What can we do?
Hi pippylu!
Please reupload the theme through ftp and let us know if that will solve your issue.
Thanks a lot
Regards,
BasilisHi,
We have reported the issue to Kriesi. Please post the FTP details here so that we can do a few tests.
Best regards,
IsmaelHi,
Thank you for the info. Did you delete this video file?
// Fran-Connect-2-0-FINAL.webm
We modified the wp-config.php file to hide the errors temporarily.
define('WP_DEBUG_DISPLAY', false);Best regards,
IsmaelThis is a dev site so you don’t need to hide it, we already have it hidden on the live site. I want to see the errors so I know they’ve gone away.
I don’t know anything about that video file – is that what is causing the issue?Hi,
Yes, the conditional function is called whenever a media file is added to the theme. Unfortunately, this function is causing an issue because the array that is supposed to be populated when calling the file_get_contents function is blank or undefined. Please try to clean up the database using this plugin.

IsmaelHi,
The error is due to the mp4 video inside the color section. You need to use the absolute instead of the relative url.

IsmaelHi Ismael,
I have exactly the same error:
Notice: Undefined variable: http_response_header in /public_html/wp-content/themes/enfold/framework/php/function-set-avia-frontend.php on line 637
Notice: Undefined variable: http_response_header in /public_html/wp-content/themes/enfold/framework/php/function-set-avia-frontend.php on line 637
Notice: Undefined variable: http_response_header in /public_html/wp-content/themes/enfold/framework/php/function-set-avia-frontend.php on line 637On the homepage of one of our sites.
I have reinstalled the theme, tested with no plugins activated, optimised the database, tried the link to a video in the first color section as relative and absolute, www and non-www, https & http.
The site is https://www.webworksuk.com/
What have we missed?
Thanks,
JoeHi,
Please edit the framework > php > function-set-avia-frontend.php file then look for the avia_is_200() function. Replace it with the following code.
if(!function_exists('avia_is_200')) { function avia_is_200($url) { $options['http'] = array( 'method' => "HEAD", 'ignore_errors' => 1, 'max_redirects' => 0 ); $body = @file_get_contents($url, NULL, stream_context_create($options), 0, 1); if(isset($http_response_header[0])) { sscanf($http_response_header[0], 'HTTP/%*d.%*d %d', $code); } else { $headers = get_headers($url); sscanf($headers[0], 'HTTP/%*d.%*d %d', $code); } return $code === 200; } }Best regards,
IsmaelHi Ismael,
That’s produced the foollowing errors in place of the orginal:

Hi,
Please ask your hosting provider to fix the problem.
It is located here
allow_url_fopen=0as they are blocking it.
Thank u
Best regards,
BasilisThis issue persists (2019-12-18, Enfold v4.6.3.1).
allow_url_fopen = 0 is a good security setting in a shared environment (notice: it also disables get_headers(), so if one is not available – so is the other!). I have a better fix for this situation, since all you really need to know is whether the remote URL exists or not:
if(!function_exists('avia_is_200')) { function avia_is_200($url) { if ( ini_get('allow_url_fopen') ) return __avia_is_200_helper_fopen($url); else if ( function_exists("curl_init") ) return __avia_is_200_helper_curl($url); else return false; } function __avia_is_200_helper_fopen($url) { $options['http'] = array( 'method' => "HEAD", 'ignore_errors' => 1, 'max_redirects' => 0 ); $body = @file_get_contents($url, null, stream_context_create($options), 0, 1); sscanf($http_response_header[0], 'HTTP/%*d.%*d %d', $code); return $code === 200; } function __avia_is_200_helper_curl($url) { $ch = curl_init($url); curl_setopt($ch, CURLOPT_NOBODY, true); curl_setopt($ch, CURLOPT_TIMEOUT, 10); curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10); curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'HEAD'); // security isn't an issue in this case, and you can skip maintaining the root CA .pem required for this curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); curl_exec($ch); $code = curl_getinfo($ch, CURLINFO_HTTP_CODE); curl_close($ch); return $code === 200; } }Thanks, ellmann_creative, that worked for me too.
I’d be bummed if I had to carry this in my child theme forever, if it’s a core issue…
