Hi. Im developing a web application in which I use linq to query data a lot. Im having some trouble querying the database, sometimes it present an error and now I can't register any user because the page throws me an error: "Object reference not set to an instance of an object." I tested it in my visual studio and it works fine, then I installed IIS in my pc and published my web application in the local IIS and it worked fine, the problem is when I publish it here... Any ideas of whats happening here?
