Hello,

I am new to DNN, and am feeling a bit overwhelmed at the moment by some of the problems that have arisen out of offering it to my customers.  The most current problem I have been alerted to is the one below, when clicking the update link on just about any page on their website.

I did some reading about this, and saw some information about compression issues, but as far as I know, I am not using any form of compression on my server (there is no mention of it in the web.config).  If somehow, DNN is using some kind of compression, how would I be able to tell?  Also, I found a sample of what was suggested to turn compression off, but all it says is to add that information to the web.config for the site with the problem... It doesn't say where in the web.config to add it (I tried adding it but it made the site stop working completely so I had to change it back).

Line: 1
Char: 1
Error: 'WebForm_PostBackOptions' is undefined
Code:0
URL: http://www.website.com/Default.aspx?tabid=40&ctl=Edit&mid=returntabid=40

Note: I modified the website name to protect my client.

Could anyone offer a bit more detail on how I can resolve this problem?  A step by step of some sort would be helpful, as all of the information I have found so far only leads me to more questions, that I am having trouble finding answers on.

Is there a standard web.config file that will fix this perhaps?
