error - An item with same key has already been added. Only on live site
hi,
I have just deployed my site (v7.3.0) and 3-4 times a day after checking the log file umbraco is throwing the below error. This only happens on the live site, I can't reproduce it locally.
It seems to happen if a user clicks a link more than once ie. double click or more. If after the error appears you refresh the page it works again...
This seems to happen on any page. I have umbraco.tracelogged my way through my master template then eventually create the error myself and each time the error is thrown after the entire master template has been processed....
