IIS issues We were receiving the same error. The solution came from our IIS settings. We used to have project Server on a separate box, and then moved it to the box with portfolio on it. The error arose because our web front end (WFE) was not pointing to the new box. (and the web front end returns html vs. xml) I am not the most technical person, so the best I can do is say that you need to check your IIS settings to make sure it is pointing to your project server correctly. |
