Error while trying to install custom theme jar.

[Felise Uy]

I keep getting an error when I try to install my custom theme plugin jar - "An unexpected error occurred. Please refer to the logs for more information."

I've included my decorator (vmd) files, jss, css and images.. Is there anything else that it needs?

Note: I referred to this document: https://developer.atlassian.com/display/CONFDEV/Packaging+and+Installing+a+Theme+Plugin

Here is what the log says:

BTW, when I view the atlassian-confluence.log, it doesn't seem to be updated with anything after I try to install the plugin.
