I have a simple Force.com site made of few VisualForce pages.
I use the same code also in Salesforce (button on Opportunity object). In Salesforce everything work very well but on Force.com site there is a bug.
Sometimes some of pages don't loading the data at all (data from an opportunity) and more than that ,when the data is not loaded in the page , this page do not appear in debug.
For example , in one of the pages , It suppose to display the opportunity products . Sometimes it's working and it is appear in the debug log, sometimes no.
If somebody have an idea ?
