I host matomo 3.14.1 on my own server, following the installation docs and everything works fine except the Manage Containers page in Tag Manager can not be load, as you can see below:
Matomo helps a lot and I've bought two plugins, Heatmaps and User flows, from the marketplace. And I also need to use tag manager, please help!
I use Safari to open this page, and it looks it's ok. But the page is still not loaded in Chrome.
for more people having the same issue. I assume most likely the browser cache still contains the old JS file before updating. Or your adblocker is blocking something important. Or you are using something like mod_pagespeed that modifies the page.
