Magento 1.9 Illegal scheme supplied

Question

Hey I've started getting this error yesterday:

"Illegal scheme supplied, only alphanumeric characters are permitted"

The error started after we implemented this fix for Varnish cache. Caracter fix

First I did, disabled the Complination manually.

Then went to phpMyadmin and checked the secure and unsecure urls: both are set to: http://www.golulo.es/, also tryed others, like http://golulo.es/etc. Nothing fixed the issue.

Checked the app/etc/local.xml and everything seems to be correct in this format:

<![CDATA[usrname]]>

The password has + in it, but it worked before, so I don't think this is what causing it.

Cleared cache manually on every change I made. I can't find where is the issue?

Could anyone point me to the right dirrection?

Thanks,

If you want to find out what's causing it to happen, you could temporarily edit lib/Zend/Uri.php which is the only place in Magento that contains this error.

Around line 108 you'll find:

    // Security check: $scheme is used to load a class file, so only alphanumerics are allowed.
    if (ctype_alnum($scheme) === false) {
        #require_once 'Zend/Uri/Exception.php';
        throw new Zend_Uri_Exception('Illegal scheme supplied, only alphanumeric characters are permitted');
    }

Add this:

    // Security check: $scheme is used to load a class file, so only alphanumerics are allowed.
    if (ctype_alnum($scheme) === false) {
        #require_once 'Zend/Uri/Exception.php';

     // temp code here
     echo $scheme;
     exit();
     // 

     throw new Zend_Uri_Exception('Illegal scheme supplied, only alphanumeric characters are permitted');
    }

The next time you get it, instead of getting the Exception message you'll see the $scheme variable that's throwing the error.
