An issue trying to validate your license / site loading issues

Hi – I have used contact@tagdiv.com as suggested in the back end, but have had no response since emailing a couple of days ago… (from luke@slicestudio.co.uk – where I’ve also given you login details)

So, despite https://brockinitiative.org/ being registered for years, seemingly after recent update the site isn’t accepting the license properly AND experiencing issues after update…

– An issue has been encountered while trying to validate your license key

Site loading issues

Here are notes on site check. Site seems to be displaying fatal error message on first load but after refreshing once or twice it is ok except for main menu blog and newsletter areas.
I tried firefox and google chrome browsers and my history clearances were basic, not advanced.

Page loaded on refresh.
I cleared browsing data (basic) and quit chrome
When I went back to check it loaded ok and on firefox – except for blog.
