Wordpress Unable to upload images

Question

For some days now, in the admin area you have had these errors:

Uncaught SyntaxError: expected expression, got '<'.

on files moxie.min.js, plupload.min.js, wp-plupload.min.js

This does not allow us to upload images to media galleries, pages, articles...

When entering in Media Gallery we have this error: Uncaught TypeError: wp.Uploader is undefined on media-grid.min.js; and no images!

If I try to upload an image from a page or post, we have the same above error but on the file media-views.min.js.

The front-end has no errors.

Some "online solutions" have already been tried, as well as updating everything, restoring a backup, installing worpdress again via ftp...

The problem remains!

I don't know how it happened, the owner of the site didn't make any operation.

Any idea?

Thanks!

Answer 1

Resolved! It was an older redirection. This redirection took all the urls with the term 'upload', so also the js plupload.min.js and consequently all the others (moxie.min.js...).

Answer 2

Are you using a cache plugin ? Sometimes using those kind of plugin can break the js for some elements.
