Drupal module updates failing through administrative interface after update to 7.50 So, I just updated my site to Drupal 7.50, and in addition to being informed of a host of modules that weren't properly uninstalled, it seems that I can no longer update modules through the administrative interface. I have a long list of module updates and it will be annoying to do all of them manually.

So is there some setting that changed? Or how can I get back to being able to update modules through the admin UI. I've tried a few at a time, as well as one at a time. I get the following warning after trying to update

The file could not be created.

This is most likely a problem with your file permissions. A quick test on simplytest.me showed that module installation is not broken in 7.50.

I would try to check the file_temporary_path variable under:

"Administrator -> Configuration -> Media -> File System"

And see that the web server can write to the configured directory.

If my assumption is correct, then also all other file uploads will fail, so it might be a good idea to test uploading an image to an article, too.
