I'm using Drupal 7 and CiviCRM version 5.13.4 and I'm having a problem with using Mosaico.

When I try to create new templates, I'm unable to add new images to them. I can't drag and drop any images or add them using the little upload icon.

When I try to do so, I get a 500 Error in the console.

 GET https://site.com/civicrm/mosaico/img?method=placeholder&params=300%2C200 500 (Internal Server Error)

I also get this error in the top right of the screen:

Failed to locate Mosaico graphics driver. Either "mosaico_graphics" is invalid or the autodetection failed.

I attempted a google on that error but it appears it's never been reported before which isn't very helpful to me.

Below is a screenshot on how the templates look to me if it's of any use:

Happy to answer any follow up questions! Thanks in advance.


I've just had a seemingly identical problem on upgrade to 5.13.5 (ImageMagick reported as missing when present & up to date).

Disabling Mosaico/Fleximailer/Shoreditch & then re-enabling them seemed to resolve the issue.

  • It's not just 5.13, I had the same issue with 5.11. Disable and Re-enable also fixed it for me. – tanbog Jun 3 at 5:35
  • Hi Bryan, I've tried what you suggested but I still can't upload images! What a nightmare! – Ember Jun 3 at 7:54
  • Same here on 5.7. Bryan's fix worked for me. – user7166 Jun 3 at 7:59
  • I've not had any problem with images. My paths & directories are default settings for this drupal install. I have had such problems on other sites when using custom settings or if the ownership of files or direcories need resetting to the web server user/group after an upgrade. – Bryan Jun 4 at 0:53
  • Hi Bryan, everything is the default settings for us too. The site is relatively new, recently changed the domain name so perhaps that is causing an issue somewhere although I wouldn't know where to look – Ember Jun 4 at 9:57

Most likely it's missing PHP's ImageMagick OR GD Extension, required for image manipulation.

One quick way to check phpinfo in drupal is to visit url https://example.org/admin/reports/status/php and see if you find imagemagick or GD related info.

  • Deepak, thank you for your suggestion but I do have ImageMagick installed on the server, you can see here - gyazo.com/498f5889bb086fbae27fb7f73dc226d6 Is there another possible cause of why images aren't able to be placed, is there some configuration that needs to be done perhaps? – Ember May 31 at 14:06
  • In that case php 500 error log should reveal the exact problem is. Could you check what it's complaining about. Drupal error reporting logs should also work. – Deepak Srivastava May 31 at 14:11
  • Other way be to debug along the lines of github.com/veda-consulting/uk.co.vedaconsulting.mosaico/blob/… and see why Imagick class isn't being loaded. Also if you search of PHP Imagick not being detected, you 'll find more help on steps to take. – Deepak Srivastava May 31 at 14:20
  • Could you tell me where the error log is please? I've scanned a few but haven't found anything as of yet. I turned on error logging in Drupal and got a few errors that I'll update my question with – Ember May 31 at 14:29

In my case, neither of the other answers solved the issue I was having although I'm sure they are also reasons why Mosaico might not be working!

In my case, it was due to a dodgy Drupal module that was injecting whitespace into all the images which caused them to break.

I set up a local copy of the site and enabled each module one by one until the images broke and then when I found the module it broke at, it wasn't hard for me to find the rogue PHP file.

There was two new lines before the opening PHP tag <?php and once I had removed this, Mosaico worked as it should normally.

  • What was the Drupal module that was causing this? I'm having similar issues. – josh Jul 3 at 0:31
  • It was one of the Gavias theme modules - Gavias shortcode. It could happen with any module though really which is annoying! It could also be the theme – Ember Jul 3 at 8:37
