Matomo was giving me warnings about using PHP 7.0, so I figured I should update and updated to php 7.2.1 via my ISP. However, after this update it Matomo is no longer working. All Matomo interface pages take a very long time to load (several minutes) and when they finish they just display the header and no visitor logs or traffic information. Interface panels for settings etc also take a very long time to load, but eventually do appear, but the panels with actual traffic information are all gone. The same for site pages with tracking, it seems that the matomo tracking code is not loading at all or maybe trying to run and eventually timing out.
I’ve tried using the System check and Activity log from the General settings screen, but these pages never seem to load. Anyone have any ideas for what could be causing this or how to get around the problem?
