Hello to all. I'm a newbie and I joined because I have an error that I just couldn't solve. It's System.ArgumentException: An entry with the same key already exists. error.
Here is the whole stack trace:
An entry with the same key already exists.

System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +2350
I can't figure out what produces the error because it shows only frequently. For example: I am browsing my website and refreshing the page over and over and it' s ok for like 10 minutes and then all of a sudden it throws an error. then I refresh it once
more and the error is gone.
I just don't know when will it show and why, but after refreshing website only once it works perfect again.
Please help me because I'm starting to freak out.
Thanks in advance,
