[I can't open my modpack]

Pastebin a log, and paste a link to it here. 

[Server Crash]

Go to the launcher, the pack you were having issues on, ModpackOptions->Open. Go into the folder config, and open the file forge.cfg. You'll see two lines, one with removeErroringEntities and one with removeErroringTileEntities. At the end, they should both say false. Change false to true, and save. Try running the pack and world again, and see if that solves the issue.

Did you fix your modpack.zip folder structure?

1) Your zip should contain three folders: Bin, Mods, and Config. Your zip should unzip directly into these folders, not a sub-folder 

2) Use forge 1614

3) Almost all your mods are from content-scraping garbage sites. Re-download from curse or curseforge, or author's website. 

4) For your dropbox link, change dl=0 to dl=1

[Game crashes when I load a world (please help this is so annoying)]

backup your world, remove the Dim Doors mod, /fml confirm when asked, stop server, re-add the mod, restart

 

If this is just a single player game, consider not re-adding Dim doors.
