Can't take modded items from crafting

[EatMyMeat]

I made modpack server, and everytime i try to craft item from any mod i cant take it from crafting table. In singleplayer it works perfectly but in multiplayer on server i made it doesnt work. It simply showed you the item on right side in crafting table, but i am not able to take it, everytime i click on it, it just jump to my inventory on second and then goes back to crafting. I think this problem is because i am starting always minecraft_server.jar not forge-universal.jar, but thats because i cant open the forge file, everytime i click on it, it just load something for second and then nothing more happens. Can anyone help? I am running version 1.7.10 of Minecraft, because i want to play one of the more old modpacks from one youtuber. Thanks
