1.0.2 RC is available. This works with Mambo 4.6.2 and Joomla 1.0.12-13. CB versions 1.1 and 1.0.2 are supported. I consider this version ready for production use. It is labeled RC, because the backend contains features that are not throughly tested. (Troubleshooter tool and online upgrades tool)
Does the paid version of your APC plug also require thedreaded Ioncbue loader or are you just using for the 30 day trial?
I can't use this with my host 1and1.com (or any of my clients for that matter since I host most of them there) and they don't support it. I couldn't even getit to run on my own testbed server at home - despite following all the instructions to the letter, it still won't work.
By using Ioncube, I think you're locking out a large perentage of your possible market - some on principle and most because the damn thing is just so hard to get working. What a shame, since APC does what we really need in CB.
