My Forge 1.7.10 works fine but my forge for MC 1.8 doesn't work. I tried the "11.14.3.1521" version and "11.14.3.1450" version. Both the same error.

    You've installed a 1.7.10 mod in 1.8.

     

    How can I fix it without deleting my mods that I use in 1.7.10 ? I use the 1.8 version to play in a server with my friend and I want to add some mods to the server.

     

    ( ps: I don't speak english, sorry for the writing errors )
