So I've looked at this post:

When trying to update indexes a get a JS error and it never finished

I added $config['assets_site_url'] = '/index.php'; to my config file but I'm still getting this error Uncaught SyntaxError: Unexpected token < matrix_multi_upload.js:166:

enter image description here

Does anyone have any other ideas on what could be causing this issue?

Matrix allows me to upload photos, but I REALLY like MMU!

Thanks for the help!

  • I am having the same error - Was this ever resolved????

  • Thanks Jeremy, I asked the question a week ago and received no responses... desperation has set in.

  • I understand. Using the comments on the question is the best place to ask questions about a question, rather than posting as an answer. There is now an answer below. Feb 25, 2014 at 19:08

That setting is "mmu_site_url" instead of "assets_site_url", for Matrix Multi Upload accessory :)


  • I'm still getting the same error. What gives? :) Setting $config['mmu_site_url'] = '/index.php'; doesn't do anything for me in my config.php file :/// It looks like it's referencing this Uncaught SyntaxError: Unexpected token < matrix_multi_upload.js:166 I even updated that file from MMU's GitHub page to no avail.

  • I have confirmed that the photos are uploading, but the rows are not being created in the matrix field. Jan 9, 2014 at 16:34
  • Shoot over CP access to [email protected] - have to take a closer look :) Jan 9, 2014 at 20:43
  • Hi Andris, email has been sent! Jan 10, 2014 at 21:45

The console log message SyntaxError: Unexpected token "<" may be caused by a missing javascript file, intercepted by some 404 or HTACCESS rule. So, ...

  • Is the themes folder for Matrix MultiUpload there, in /themes/third_party/matrix_multi_upload?
  • Is it accessible over HTTP?
