Modpack Installation not working correctly

[Serst]

Hi,

 

I tried uploading a Modpack last night with around 119 mods, when I compressed & archived the files and uploaded them to dropbox, I put the download link into the "Modpack Location" section of the Edit Modpack. When I went around to installing it, an error came up with the text:

 

"Invalid URL (url here)

Please contact modpack Author"

 

I've scoured the forum for fixes but nothing seemed to work, I mindlessly clicked through videos on how to install Modpacks and to no avail, none yielded my precious install. I'd much appreciated some help here as some friends and I want to try out the Modpack on our server.

 

Thanks, 

Serst
