I do not guarantee this will work for you but this is what I did to get my server up and running:
1) Back up your server files!!!
2) Copy your client mod files over to the server, including config files
3) Open PortalGun_Server.properties, find and change the following lines to match below:
idAFP=1100
idPortal=1101
idFizzler=1102
4) Delete Forestry, InvTweaks, ReiMinimap mods
5) Restart server
