Go google what this error means: Unsupported major.minor version 52.0

Modpack works fine from what I see? What isn't working according to you?

I'm afraid your questingdata got corrupted.

Important question but have you used something called MCleaks? If you did, look on their website how to remove it.

What's the name of the modpack, and is it your own modpack?

Remove Java 8u221. After that, install Java 8 from this link: http://javadl.sun.com/webapps/download/AutoDL?BundleId=98428 Start up the launcher and try again.

Don't play pixelmon.

From the Smooth Font page: "If you want to use this mod with FastCraft on MC1.7.10. Please specify "enableFontRendererTweaks=false" in FastCraft.ini."

99.9% chance you are either allocating too much RAM now, or you need to downgrade your java to 8u51.

"wouldn't work" describe what isn't working.

Modpacks started fine for me. No vanilla issues.

Did you read how to make modpacks? What should go into the bin folder? And what is currently not in the bin folder?

Why did you add legacyjavafixer (a 1.6.4 mod) to your 1.12.2 modpack? You need to downgrade your java to 8u51 because your intel graphics card can't support higher. Unless your drivers are woefully out of date.

You forgot to include Openlibs.

Your downlink link is dead anyways. Only paid mediafire's direct download works, the only free alternative is Dropbox. Also, you included Journeymap twice.

1.) You don't want to know why there's a dong emoji, but it has something to do with the past. 2.) So you just want another kitchen sink modpack? Just with an official tag this time?

That's not an adult dragon...

No, this isn't your issue, go make your own post about it. And include logs.

*Any* actual system information would be great.

Probably has something to do with the fact that you didn't get your mods off Curseforge. Also, coremods folder has not been used since 1.5.2.
