Ok.

So, first, change the "1" in the pack.mcmeta file to a "3". (If you want to keep the 1.7 version, make a copy of the resource pack beforehand.)  This should allow you to apply the texture pack in-game in 1.11+.

Then, go through all of the textures and make sure all of the file names are completely lowercase. If some of them are not, change them to be lowercase, with underscores where there would be spaces. (For example, "enderDragon" would become "ender_dragon".)

Theoretically, it should be compatible with 1.11 now, and all the textures should work well. If not, I can troubleshoot it a bit more.
