There seems to be a disconnect between “your plugin is broken” and “your plugin no longer works with my custom theme”. Please realize that by custom theme I refer to any theme other than TwentyTen, TwentyEleven, TwentyTwelve, and TwentyThirteen. And even amongst those themes there still may be minor issues with font size, spacing etc. To truly understand “your plugin is broken” I would expect the “white screen of death” from a PHP Fatal Error. Or even a calendar or event listing that doesn’t render, most other issues are largely related to conflicts between plugins and themes.
If you want to vent, by all means, it’s a public forum. If you want help fixing the problem create a thread with a clear question. Provide a link so others can see what you see and try to provide a detailed description of the problem. Please read the Themer’s Guide. Create a child theme off of your current theme. Try to create you own ‘tribe-events/tribe-events.css’. It will greatly assist in keeping your solution intact through the updating process.
If possible create a local test environment of your blog and test there. It makes it much easier to test things rather than screw up your live site.
Lastly, please don’t hijack threads. If your problem isn’t the same as the OP, start a new thread.
Most of us are here helping because we can. I’m just a customer of Modern Tribe. When people just start venting it doesn’t look like they’re looking for answers.
I hope everyone’s day gets better.
