XML Parsing Error: syntax error Location:

[ravininave]

Hello,
've developed web application using ASP.NET VB and I deployed it on shared server (GoDaddy). On My Login (After Login submit) Or on Registration (After Submit) I got the error

XML Parsing Error: not well-formed [SOMETIMES Syntax Error]
Location: http://www.myurl/
Line Number 1, Column 36:

Data is saved in db but it shows this error. If I press f5 then it goes to next page. I goggled for various solutions but none of them worked. I'm not using any XML Data related command. Even I tried it after disabling all the JQuery.

Can anyone suggest something on this.?

One more thing if it helps sometimes it shows data from _EVENTVALIDATION tag like
