    Hi There, I've got a problem with a simple form with button postback, it gives me the following issue, however, if I refresh the page cup of times it seems to be gone away.

    Also if I open fiddler, the problem gone away too, very strange.

    Any suggestions?

    Webpage error details

    Hello Leong,

    The mentioned error most commonly appear in case you are using trial version of the controls. The trial message uses Response.Write() method to appear and this method is not supported with Ajax. As soon as you upgrade to licensed version the error should disappears.

    You could also take a look at the related forum posts below:

    Hi Maria, thanks for the reply.
    I am using full radcontrol version 2013.3.1114.40 (which is what we licensed for).
    The issue doesn't appear until we postback and browser cache is cleared, and seems only happen in IE.
    Another thing I am current checking with our system eng is the firewall setting which potentially causing it as it use to run fine until we have relocated our server.
    turned off radcompression, will check the links you've provided, thanks.
