I encountered a very strange recording.
I recorded a HTTP script in the VUGEN which came out with most of transactions with empty code.
I deleted the cookies and all other options of the browser.
I must mention that I recorded the same script a few months ago correctly.
Is it something in the record settings, general options or other place which might have caused it or even the application itself?
Go through the changes made to your environment since the last time this worked. This may include software, configuration changes, rights changes, etc... Eliminate them one by one until you get back to the last working config. In this process it will become evident which of the changes was the offending element.
