This was working a week ago with PHP7.2 and the previous Filerun. People using shared links successfully uploaded files to our instance of FileRun.
Then, my server provider encouraged upgrading to PHP7.4, so I did. At the same time I upgraded to the latest version of FileRun 2021.03.26. I had to upgrade Ioncube, too. Now everything works, except for users of shared links are unable to upload files, getting the message "The followed link is not valid."
I tried it, it appears to upload normally. But then that message appears.
You can try one of the nonworking shared links (password is "JF"): [edited out]
Any insight will be greatly appreciated. Thanks.
