Title says it all :) New registered users are unable to see the Wiki unless I manually add them to the Admin group.
Also the new users get the following error message when they log in:
[d294338f691249591147199f] 2018-01-24 18:46:47: Fatal exception of type "Exception"
After refreshing the page a few times, they are eventually able to see the Wiki main page.
Thank you so much!
