I have a client using version 3.0.8 PRO that I installed for them years ago. It's been working fine on Windows XP. They are wondering whether there will be any issues if they upgrade to Windows 7. I don't think it would have any effect but I want to make sure. I'm also wondering whether there are any other issues to be aware of going forward. Funds are tight so they'd like to continue using it if they can. Thanks for any info you can provide!
OS does not matter. It depends on Webserver, PHP and MySQL that you use. Version 3 is very outdated. I suggest to consider migration to latest version (5) http://www.amember.com/docs/Migration_from_legacy_aMember_Pro_v3 Best Regards.
