Can you share the name of the config file in question and maybe even the line that enables debug by default and how it should be instead?
One thing our clients check is if there is an edited userconfig file, if so, we don't update them to avoid loss of your changes. This can mean that it's a setting enabled by yourself at some point.
We normally don't alter the data, as we're not the authors, but are more than willing to investigate if there is a difference in our version compared to elsewhere and if it makes sense to change the 'default' version
Issue #1 is clearly a bug as the page where the arma 2 logo links to doesn't seem to exist anymore, luckily we are already in the process of updating our homepage so issues like this should be resolved soon.
