Nevermind—the problem resolved itself when I tried using Safari instead of Chrome. I'll leave this post in case someone else runs into the same problem.

I followed the steps for updating from version 3 to version 4, described here: https://www.admidio.org/dokuwiki/doku.p ... _version_4. However, I'm now getting a 500 error when I try to access Admidio.

When will that version be released?

Version 3.3.17
