The name of the profile is "1.12 - forge", however, that doesn't mean anything. You have a profile running Minecraft 1.6.4 and have it called "1.12". To change the version, click the "Launch Options" at the top of the launcher. Click the profile you want to change (in your case "1.12 - forge"), and change the version to the Forge version you installed.

Yes, right under the big, green "Play" button, it says which profile you are running. Make sure that profile has selected the Forge version and not vanilla Minecraft.

Make sure your profile has a Forge version selected from the version list.

I think you need to have the type as "minecraft:crafting_shaped".

I haven't done this in a while, but I think that if you set the "y" tag to 90, any rotation on the x-axis will apply to the z-axis instead.

Minecraft and Forge didn't add the "z" rotation tag because you can replicate it with a combination of the "x" and "y" tag.

You need JSON files for recipes now. Look at how vanilla does it.

These 3 mods errored, try updating them.

The log doesn't show anything out of the ordinary. Is this the log with the mods which don't work?

Post the FML log (logs/fml-client-latest.org in your game directory).

Optifine requires a specific Forge version, read the install instructions.

Update the Traverse mod.

That's not the FML log. The FML log is a file called fml-client-latest.org inside the logs folder of your game directory.

You shouldn't. If you have a profile in the Curse/Twitch launcher, you can just click run and it opens the Minecraft launcher with the correct information, so you can just run the game.

Do you get any errors about recipes when loading the game? I'm asking because JSONLint gives an error at "A": [ { "item": "minecraft:stone", }, ] as you have a spare comma after the "item" tag. Other than that, I can't see anything wrong.

Does the path actually contain "modid"? Because it should be the actual modid of your mod.

1.7.10 is no longer supported on this forum. Please update if you want help.

Add this: "custom": { "flip-v": true }, to your blockstate file, next to where you specify your model.

Post the FML log (logs/fml-client-latest.log in your game directory).

Images should have a square size which of a power of 2, so 16x16, 32x32, 64x64 etc.

The Twitch/Curse launcher will notify you if there's a mod update. If you click the button to update, it automatically removes the old version and replaces it with the new version.

You should look at the mods you have for 1.11.2, not 1.10.2, as you're running 1.11.2 according to the log.

If you use Block#onBlockPlacedBy, you'll get the EntityLivingBase who placed the Block as a variable.
