Hello flupke,
I have already made the upgrade from 8.1 to 8.3, and I'm having problems with all SiteBuilder's custom buttons.
The 8.3 version does not use the Custom Buttons, SiteBuilder and Plesk are now "integrated".
The old Custom Buttons were not "converted" to the new integration style, and they didn't work anymore.
But who cares at SwSoft/Parallels?
I have made some tests before upgrade, but as you said, you just can't test everything.
Unless you are the software developer, with milions of customers and revenue, generally you don't have resources (hardware, software, time) to test a product that should be tested enough by the software provider.
Yes, there are may versions and plataforms, but if they can't manage all of them, then I think they should limit the options. Too much work can't be never the excuse to make bad work, do you agree?
I'm using a plain RHEL5 OS with Plesk, nothing more, and I never had a smooth upgrade. Never (I have used RHEL3, RHEL4, RHEL5, Plesk 7.5.4, Plesk 8.1 an now Plesk 8.3).
Thank you for your reply.
