Some issues I noticed.
1. In activities, it's impossible to make a comment on any activities. The ACL setting is allowed. This goes for registred users and super user.
2. Backend->Configuration->Integration, I have the settings as follow
Load Bootstrap CSS - No
Default Layout - Botstrap 4
Then, no matter what team is selected, teams are not functioning, is this because of Bootstrap 4?
3. Header area is quite big (compared to your demo site) is this also because of Bootstrap 4?
4. In profile, tabs ordering. How to change the order of tabs that are showing?
Nr 2 and 3 is also for cjforum.
Any ideas how to fix theese issues?
If the problem can be solved why worry?
If the problem can not be solved, worrying will do you no good.
