Ultimate Member on "Ultimate Member blocks file uploads in Gravity Forms"

Hi, I am testing Ultimate Member and am very happy so far. Unfortunately I found out that the plugin seems to block file uploads within Gravity Forms. When Ultimate Member is activated, I get the following error when trying to upload a file with Gravity:

Error: -200, Message: HTTP error, File: xy.pdf

Any help is appreciated. Thanks!

Hi,

What version of the plugins are you using? We use Gravity Forms on our website and people can upload images.

Thanks
