Hi,
I've just checked the last 12 sites I've created using the T3 Blank Quickstart - and they all have the Tag Manager missing 🙁
I'll try to test a new install of the T3 Blank Quickstart on the same server as my customers sites, as the one I just did locally on my MAMP, was working fine. Maybe it has something to do with PHP version or other server related things...
So I'll be back with more info 😉
Thanx for your help so far - appreciate it!
Cheers
