When accessing Greta's Genealogy Bog today I first noticed that it took one to two minutes for the page to load. Then when I went to the "Layout" page only the top section would appear; it took another minute or two for that to load.
I googled various word combinations having to do with blog problems and finally found some advice to check Activity under Window. That revealed that the problem involved the Contact Button. It was then that I noticed that my blog no longer showed the Contact Button. I visited several blogs that I remembered having these buttons, and none of them appeared to have it any longer, either.
Update: Today (Monday) the Contact Button seems to be working and the blog seems to load OK. Not sure what happened. Some type of Blogger maintenance maybe?
