Strange bug which sometimes happens.
I tick the users who I want to be able to see this mod and it all works fine.
Then for some un known reason they all get set back to being un-ticked.
This has happened a few times, but one now and again.

any ideas?

I haven't seen this on my site and nobody else has reported this.

Is it possible that someone else is resetting the usergroups without telling you?

don't work vb 4.2.0 :(

Yes it does :D

Installed it but it will not allow me to save any of the selected Usergroups

Doesn't seem to for me on 4.2.0

Ok I got my story sorted out. I am using the Advanced Product Management and when I used this I could not save it. However if I go through the normal way Options/OS/Browser Display Settings it works 100%

It does work on 4.2.0. My site uses this and it is running 4.2.0.

Are you making a new post? The mod can't display the OS and Browser for old posts because that info wasn't collected when the old posts were made.

Did you upload all of the files to the proper locations?

Did you turn the mod on in ACP->Settings->Options->OS/Browser Display Settings?

Did you set the usergroups that can see the OS and Browser types? At least one usergroup for both OS and Browser must be selected.

Advanced Product Management will not work with most of my mods that set usergroups using checkboxes or radio buttons.

nhawk on your forum it shows the Blackberry icon but when I installed it I see the ? unknown icon. Also nothing for Tapatalk at all just a blank.
