[HttpException (0×80004005): Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster.] This error message seems to be pretty thoroughly documented for asp.net, but how do I fix it in ASPRunner.Net?
OK, well....after struggling with this problem for hours! I finally figured it out. So I'm posting the answer in case anyone else runs into this. I put this code in my web.config that I got from the site... <authentication mode="Forms">
</authentication> By default it uses <authentication mode="Windows" /> But I'm using shared hosting. Sooooooooo
If you actually read the article timeout="30" is 30 seconds. So when I'd login I couldn't go anywhere else after 30 seconds. I just removed the timeout setting. Problem fixed.
