So i have a friend on a server called simplify minecraft and recently whenever he attempts to login he gets this crash report

You have some 1.7.2 mods in there.

So the 1.7.2 mods are conflicting wth the 1.7.10? If so can you please list the mods that need to be removed

You don't have to remove unless there's no update for 1.7.10.
Just go into your mod folder. Look at file names. Half of them will have version listed right in the file name. Of the ones that don't, check manually the author's page on minecraftforum.net or planetminecraft.com or curse.com and see if there is a separate 1.7.10 version and if 1.7.2 one will work on 1.7.10. If there isn't a 1.7.10 version and the author doesn't specifically say it'll work on 1.7.10, then take it out.
