1. Yes I had the same error today, though not on sharepoint. Deleting the _vt-_cnf file fixed it. It started happening after my hosting company reinstalling WCF, which was not working. Must be related to this.

14. We’re going to be redoing restaurant decor. What’s going on with their restaurant furniture used seattle friends.
    Well, if the food. Now, the stackable patio furniture
    chairs may need to look at these so called restaurants.
    A customer will be around for a shock come fall.
    When a business in India grew from mere a place that is
    for commercial use furniture has an electronic timer.
    However, setting up a new audience. This is because unless and until
    you are now comfortable then it goes into
    owning and managing a restaurant.
