I recently purchased a hosted server. The server starts up with the TekkitLegends jar file but doesn't recognize plugins, so I assumed I needed to use a cauldron file. This doesn't start the server whatsoever.

The problem seems to be that there isn't a tekkit legends jar on the panel that allows for the use of plugins. I do not know how to recitfy this. I uploaded my own jar file that I use in the home hosted version of my server but that doesn't seem to work either.

The panel is multicraft and the host is ggservers.

I am an experienced server creator, don't be afraid to use complex terms.
