Hey, Adobe are struggling to replicate the issue I detail in 'Have found some evidence for that "There was an error accessing this page. Check logs for more details." issue in CFAdmin', and raised as ticket 3810459. Which Adobe have closed as "works OK on my machine".
This is the situation in which CFAdmin will sometimes present this error when trying to make settings changes:
If you have experienced this, could you pls chime in on 3810459? Even if you haven't solved it, providing Adobe more info would be helpful. Plus would help them realise it's a real issue that impacts a bunch of people, not just me and the other bod who has commented.
