Yes, you are correct on both counts. I had this problem on Thanksgiving Day but it resolved for some reason. It returned this past Saturday and has not resolved. I am primarily an end user and am worried about uninstalling plug-ins and changing themes. Have never done these things. If I deactivate the plug-ins will it change things on my website that will not be retrieved?
Seems to have cleared up. Must have been an issue with my ISP.
