I've been trying to work on my website for several days, and I have two separate problems that I have traced back to Avast. My Pro subscription expired, and I assume that's what led to this situation. Unfortunately, paying to upgrade to pro once again did not fix it.
First, several homepage widgets were blocked from appearing. This is resolved by enabling secure DNS, so that's fine.
Second, and more importantly, I can't SEE my updates on my site. I have already cleared my browser cache, website cache, flushed the DNS, tried viewing in different browsers and in incognito mode. The only reason I believe this to be connected to Avast is because when I repaired the install yesterday, I had approximately an hour that everything worked perfectly before I was back in the same situation. Then at one point today I had my updated footer revert to a previous version. How does that happen?!
