When trying to publish a page within Sitefinity 3.2 I keep getting the following error.
"Invalid postback or callback argument. Event validation is enabled using
<pages enableEventValidation="true"/> in configuration or <%@ Page
EnableEventValidation="true" %> in a page. For security purposes, this
feature verifies that arguments to postback or callback events originate from
the server control that originally rendered them. If the data is valid and
expected, use the ClientScriptManager.RegisterForEventValidation method in order
to register the postback or callback data for validation."
for test purposes I have tried adding enableEventValidation = "false" to my web.config, didn't work.
The same thing happens if I click on the "Cancel changes" link. I have read through everything in the User Manual and tried every setting in IIS that I can think of.
I have read similar post with the same error, but they all seem to relate to AJAX controls within the page. I am not using any AJAX within my pages. All of my pages are very basic using the "Generic Content" control.
Any suggestions would be appreciated greatly. Thanks
