As of this morning, there are four problems with the site (applebrides.com) that weren't there yesterday.
1. Two plugins are acting strange. There's an ad plugin in the sidebar (adrotate) which does load, but none of the ads come up. This is the "Featured Vendors" widget. No popup/ad disabling was active on the browser.
2. The other plugin is a social media one that displays at the bottom of each post. Facebook share and tweet icons don't show up. Interestingly the tweet icon is restored if I turn off the adrotate plugin.
3. The black bar along the top when I am logged in and viewing the site has disappeared. It remains on the backend.
4. Not sure if this is new or not, but when I hover over an unclickable part of the site, I see applebrides.com/wp-admin/update-core.php in the status bar of the browser.
I have restored the database to yesterday when all was still working, but that has made no difference. I have also reinstalled wordpress with no change. What else can I do, and what is going on? I am totally baffled.
