Trying to make a personal custom modpack, and getting so many errors on MultiMC

[TheDarkSeraphim]

As the title says, I am getting a bunch of red errors in MultiMC while trying to make my own modpack, for personal use.

The game launches and I can play it, however, I want it to work as compatible and smoothly as possible. So I want to remove as many of the errors as I can.

If you need any more information, I'll be happy to help to get this sorted.

Part of modpack making is being able to read what is going on in the pack. A good what to see what is red as its loading is to search (ctrl-f) for error. That being said, while loading there are going to be errors and nothing can be done about them. Some errors just point to the fact that they can't load a certain part of a mod. That is normal. Looking through the errors, none of them are out of place, so they can be ignored.

@FallenEagle1 Thanks for the quick response!
That's good to know that none of the errors are especially bad, it definitely a relief, however, I do notice while going through JEI to check all the items, some have the black and purple texture, and also that some items are named incorrectly (I'm sure you know what I mean, a string of a few words with periods instead of spaces).
Also, when creating a new world, under "world type", it comes up with "generator.nether" and "generator.The_end", do you know what is causing this?

One last thing, since you said that that nothing stand out, I added in the last few mods that I wish to have in the modpack, and again, got so much red and yellow text, would you mind seeing if anything stand out as something fixable?

Thanks for the support!
