Hi,

I don't know whether this is a correct palce to post my thread. Please guide to get on to the right direction.

I am new to DNN..I have my website installed and running, but today morning I noticed an error soon after opening my site homepage.The error is:

A Critical error has ocurred.

Item has already been added. Key in dictionary:dnn.xmlhttp.js' key being added:'dnn.scripts.js'

When I restarted the browser. Itwas working fine. Now do I need to worry about it?is that something related to DNN or my browser?

Please help

Thanks In advance.

Thanks for getting back to me real quick Mitch.

Hi,

I have a similar problem and could not find an answer in this post.

I've got this error while playing with a new module I am testing. I went to Host->Extensions-> Edit my new module and added a new control. I did not enter a new key, hoping it will tell me my error. Instead it does not let me modify my module anymore, and every time I try it gives me this error:
