Won't Activate Plugin

[trismegistis]

Hi I try running the plugin but it doesnt generate the folder in the plugins or get listed with /plugin.

I don't have mysql running, but shouldn't it have made the folder first?

Do you have write permissions for the plugins folder? Yes, it should've made the folder first. Does the log say anything interesting?

No logs. I'm on kcauldron 1.7.10, and tried all available versions. Any libs?

The plugin was explicitly designed for 1.8... not sure if it is compatible with KCauldron or 1.7.10.
