My mods all seem to work properly when in single player but in my Forge Server it doesn't!

On Creative, I can give myself say a block from the mod and it's physically in my inventory but when I place it down it appears for the slightest of a second then it disappears. Please Help!

 

Note - I have already made sure that my Jar File mods are in both my local game and the servers mod folder.

I'm launching it through my own computer. I just got it to work now realizing that I just needed to copy the config from the my local file to my server config file. I do ask however, must I do this every time I install a mod? By the way I'm surprised you responded so quickly, I respect your work!
