Mod Pack Suddenly not working

[mrhuggalumps]

So I have my modpack and everything was well. It was working fine earlier today but now, I get an error saying forge is out of date despite the fact nothing has changed within the files. Is this a known error or has forge spontaneously reverted to an earlier stage?

Always provide the API URL or a link to your pack details page when requesting custom modpack assistance.

• You have a coremods folder with something inside of it. Forge for 1.7.10 (actually >= 1.6) does not use a coremods folder in any way. All mods belong in or below the mods folder.
• I'll take another look after you provide the API URL because your pack works fine in my test environment.
