Mods button in main menu gone

Lanatir · May 14, 2015

Ok, i have been trying to get mods to work in my minecraft installation for a while now, and yes, i have been reading the rules on what to do before posting. I googled my problem, but it seems to be unique. Also, I am unsure which log exactly i should post here, because not all of the logs you request to see even exist in my folder.

I am running a fresh installation of Minecraft 1.84. I am using the newest Installation of Minecraft Forge.

My Operating System is Windows 8.1

Here is what i do, step by step:

Install Minecraft 1.84 clean and fresh. Run it once.

Install Minecraft Forge, run it once on 'latest' Version. The 'Mods' Button is there in the main menu, all good and fine.

Next step i do is: Edit Profile, change the Use Version to 1.7.10 cause all the mods i want to use (that are correctly placed in the mod folder as .jar files) are of that Version. Save Profile.

In the Minecraft Launcher I do see now that tha Forge Profile uses the correct 1.7.10 Version i wanna use.

I press play, Minecraft starts.

No Mods button. Its simply gone.

And from that moment on, no matter what i do, no matter what version i switch to, the mod button stays gone. I have to completely uninstall Minecraft and reinstall it fresh with Minecraft Forge to get the button back. But since not a single mod even exists with the latest Version of Minecraft i basically can not mod at all.

Help!

And please tell me which logs exactly you want me to include, cause i dont understand which one you want from the description you wrote.
