I had to reinstall my site from a backup, as it suddenly started saying on google that the page wasn't mobile friendly, I think from an update but I'm not sure which. Previously I also had 4.9 score reviews via Facebook on my google search listing but that has suddenly disappeared and I don't know why. So I reinstalled a backup to try and get it back, but it doesn't seem to have worked. I had to reinstall the yelp review plugin also, and I've set it up like before and told it to appear in the widget side bar on the left with the other reviews. But it won't appear and I don't know why.
So I have two issues - firstly what has happened to my site to make my facebook reviews disappear from google search in the last few days, and secondly why won't the yelp plugin appear where I've told it to?
