When I try to upload an image through anything other than the admin/content/media interface, I get an "Drupal.media is undefined" error.

Uploading an image through the interface does work. Using the Firefox developer console I can search all files (!drupal.media). It finds something on admin/content/media but nothing on other pages.

I do have the Media module installed, and I am aware of the following modules being affected: md_slider and stability (a theme).

Why does this happen, and how can I fix it?

  • Can you please provide a list of the modules using as also the console log when the error appears? Also, since the theme you are using is not free this might be a problem with testing. Jan 8, 2015 at 10:56
  • @TheodorosPloumis please see the updated question. I am afraid it will be more difficult. I have already contacted the creators of MD Slider though I have not got any response whatsoever. Jan 8, 2015 at 12:50
  • Could you disable javascript-aggregation, so we can see which js-file causes the trouble?

  • Yes, error is on: md-slider-panel.js?nhuw2e:7 I already contacted the maintainer of md-slider though I have not heard anything from them. Jan 15, 2015 at 10:09

I am afraid this error comes from the jQuery version.

Since you have the jQuery_update module check if the admin has the same version with the frontend. If not change the jQuery version of the admin to be the same as the frontend's (this can be through the modules UI page). Then, check if the same error occurs on the admin page. If so you have to test the frontend with other jQuery versions.

Notice that in case you cannot use the proper jQuery version for the frontend (since there are confilcts with other modules) then the only solution is to disable these modules or override them.

Before that, maybe you could use the latest dev versions for media, jquery_update modules and check if the problem remains.

  • Thanks. I have already tested with some (not all) versions of jQuery through the module config page, I'll test different combinations and let you know. Jan 8, 2015 at 14:15
  • I tried the different combinations though it did not help. I'll try the dev versions after I've annoyed the maintainers of md-slider some more Jan 15, 2015 at 10:11
  • @AmazingDreams If uninstalling the md_slider module solves the problem then, yes, this problem causes the problem. Jan 15, 2015 at 14:57

I contacted the dev of the stability theme. He gave me a link to update the md_slider module to v7.16.

This fixed the issue
