CE Image configuration for MSM

Question

have an MSM site that I’ve just moved from test to production and we’re white screening on the front-end. I suspected CE Image straight off - commented out my tags and sure enough, the site loaded sans images. I’ve set 128M for CE Image via the config file and then inside index.php we’ve got

$assign_to_config['global_vars'] = array(); // This array must be associative
$assign_to_config['global_vars']['ce_image_document_root'] = '/home/user/public_html/msm-site/';
$assign_to_config['global_vars']['ce_image_src_regex'] = array();
$assign_to_config['global_vars']['ce_image_made_regex'] = array();
$assign_to_config['global_vars']['ce_image_encode_urls'] = 'no';
$assign_to_config['global_vars']['ce_image_disable_xss_check'] = 'yes'; 

This works fine on the test server (although we didn’t set the memory limit on test). Interestingly though, the config file editor in the CP is showing ce_image_memory_limit set at 64 and even changing it there isn’t allowed. Where’s it going wrong?

Answer 1

You need to fill in the array for all of your domains that are part of MSM. I copied this from config.php for a 9 site MSM install and reduced it to just 3 sites to demonstrate:

// ce_img stuff here
$config['ce_image_src_regex'] = array(
  '^http://maindomain.com/' => '/var/www/vhosts/maindomain.com/httpdocs/',
  '^http://domain1.com/' => '/var/www/vhosts/domain1.com/httpdocs/',
  '^http://domain2.com/' => '/var/www/vhosts/domain2.com/httpdocs/'
);

Once you fill in the correct domains and server paths, you should be good to go.

So it turns out to be a server issue where GD support hadn't been enabled in PHP.

Enabled that, kept the same code and we're golden :-)
