I'm running stable 126.96.36.199 on Debian Squeezy.
Delighted to see the APS installer pop up on there, a very useful tool I'm sure and one I'm keen to tell my clients about.
Unfortunately the APS installer only appears for admin users. I'd have assumed that it would be available to clients but of course limited to their own sites.
Is this by design or is something up with my ISPConfig install?
SOLVED: I've discovered that there is a limit to APS instances in the Limits section of the client configuration. For some reason the APS instance limit had set itself to -1 for most users but 0 for others.
