I am modding Minecraft 1.7.10 (really love 1.7.10 mods) and it crashed before the game even loaded. I set the launcher up to open the game output log and one very big error line stood out to me with this exact line: Caused by: java.lang.ClassNotFoundException: net.minecraft.block.BlockOldLeaf I'm not sure what it means by BlockOldLeaf but I have an idea.
I think the client is trying to load an "impossible" block; that is, to say, a block that doesn't have properties or has missing properties.
Here is the full error log:

I have an idea of which mod it may be :
However I have many new mods from last time I modded 1.7.10 and can't say this for certain. Also, the only errors I got last time I was modding the game were missing core mod files for such and such, which were easily fixed.
Confirmed that Ancient Trees aren't causing the crash, last 30 lines before crash:
