Whenever I add any content on my website, I get this warning.

Warning: in_array() expects parameter 2 to be array, string given in _drupal_http_use_proxy() (line 1100 of /var/www/html/includes/common.inc)

I am not sure why it does that, and how do I solve it? Can anyone help?

PS: I don't know what tags should I use for this question.

This is the code for _drupal_http_use_proxy

function _drupal_http_use_proxy($host) {
  $proxy_exceptions = variable_get('proxy_exceptions', array('localhost', ''));
  return !in_array(strtolower($host), $proxy_exceptions, TRUE);

The status message warns that $proxy_exceptions is not an array.

You can configure this setting on your settings.php file, this way:

$conf['proxy_exceptions'] = array('', 'localhost');

Have you changed this variable to anything other than an array?

 $conf['proxy_exceptions'] = ''; // For example

Maybe there is a contributed module which do this...

Try to insert a dpm on $proxy_exceptions or execute this on /devel/php to show the value of this variable:


If you want to reset this variable:

variable_set('proxy_exceptions', array());


  • Hi, Thanks for answering. I have checked my settings.php file and I have this data but it is commented by default and I haven't changed anything. Here is the data # $conf['proxy_server'] = ''; # $conf['proxy_port'] = 8080; # $conf['proxy_username'] = ''; # $conf['proxy_password'] = ''; # $conf['proxy_user_agent'] = ''; # $conf['proxy_exceptions'] = array('', 'localhost'); May 9, 2014 at 14:28
  • Have you checked what is the value of this expression: dpm(variable_get('proxy_exceptions')); on /devel/php

    Then reset the variable: variable_set('proxy_exceptions', array());

    The proxy_exceptions variable was corrupted on some point. You have reset this to a proper array() value.

I couldn't solve why I used to get the error messages, but I hid the errors and warnings for the everyone except admin using Disable Messages module. It's quite good, all I had to do is install the module, and change the permissions according to roles.

I will update my answer if I found the way to solve this warning.
