Hi All, I do have the same error. My application in ASP.Net 2 connecting to ORACLE and I'm using Master page for the front-end and one other for the back-end and I faced the same problem when I publiched the web appliction from VS 2005 and deployed it either to IIS 6 on XP OS or IIS 6 on Windows 2003. I'd deployed before one working published version and it was fine. I think the main point is coming from the MASTER PAGE for the front end as I'd changed it then the error appears, in the main while the back end that uses the other Master page is working fine, I think if we re-create the MASTER PAGE it would work fine. --- please, if anyone solved the problem before me let me know. ---- :omg: Regards
