In order to root out one of the more common issues, we'll need to see your hosts file. Here's the steps to getting this file.

1) Press the Win + R key on your keyboard.

2) Paste the following into the prompt that opens: 'notepad %windir%\system32\drivers\etc\hosts'

3) Use Ctrl+A to select everything in the file, then Ctrl+C into the textbox to post to this thread.

Found java version 1.8.0_51

Upgrade your java. The version you are using has expired trust certificates.

Boilerplate:

If you don't post your logs/debug.log we can't help you. For curseforge you need to enable the forge debug.log in its minecraft settings. You should also post your crash report if you have one.

If there is no error in the log file and you don't have a crash report then post the launcher_log.txt from the minecraft folder. Again for curseforge this will be in your curseforge/minecraft/Install

Large files should be posted to a file sharing site like https://gist.github.com You should also read the support forum sticky post.

How Can I Safely Play an Old Version of Minecraft?

Yeah, you can safely play Beta 1.7.3 using the official Minecraft Launcher. Just create a new installation, pick the old version from the list, and set a separate game directory so it won’t interfere with your current saves. The main compatibility issue is that old saves may break if opened in newer versions, so always back them up.

Mod for world Templates

No, there isn’t a dedicated Forge mod for world templates in 1.20.1. Your options are to use datapacks for custom worlds or run the Fabric mod through Connector.

How do I remove 3d headlayer on NPC's skin in CustomNpc? (1.16.5)

I do have to add that this is my answer for 1.12.2 but it should ALSO work for future versions.

How do I remove 3d headlayer on NPC's skin in CustomNpc? (1.16.5)

I know this was posted almost 3 years ago but this is for anyone who is still looking for an answer.

First, find your config folder. -> C:\Users\ (desktop user's name) \curseforge(or the application where you've downloaded you mod)\minecraft\Instances\config (The config folder should be in the same folder as your mods folder.) Once you click on the config folder, search for CustomNpcs.cfg. Once found, click on it (you can edit it using notepad) and search for the line "headweartype". Set the value to 0 if you want a 2d head layer, set it to 1 for a 3d head layer. Then save the options and you should be good to go from there! :)
