Hi there,

I am experiencing the WebForm_DoPostBackWithOptions error, as well, on a fresh 4.03.03 install:

WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("dnn:ctr567:SiteSettings:cmdUpdate", "", true, "", "", false, true))

Regarding the suggestion that the aspnet_client directory be added;

1. What is the proper way to add the aspnet_client directory? Can it simply be created using Windows Explorer or...?

2. What are the correct contents of the aspnet_client directory ?

3. Does the aspnet_client directory need to exist in the web root, the virtual directory root, or both, or...?

I apprecaite your help!

Bill
