How to install Toomanymods for Tekkit 1.1.8?

[Envouz]

I have been having the issue with the login to my server where it says

"Forge Mod Loader has found ID mismatches

Complete details are in log file

ID 102 is mismatched between world and game

ID 335 is mismatched between world and game

ID 79 is mismatched between world and game"

This issue has been brought up in this forum "http://www.minecraftforum.net/topic/1916001-forge-mod-loader-has-found-id-mismatches/" and supposedly has been fixed from using Toomanymods but how do you install it for Tekkit?? There are no videos on Youtube about it so I thought I would come here.

Thanks!

I don't think you'd have to install this "toomanymods."

Did you maybe forget to update your server from 1.1.7, or maybe 1.1.5, or even 1.0.6?

FTB is currently experiencing a similar thing with one their packs, turns out some of the mod's just changed their item name between versions (eg. extratrees.<something> has become binniescore.<something>) could just be this, try pressing yes and see if your world is broken in anyway.
