I'm trying to host a server with mods but I get this error

[DoggoDoggins]

I'm trying to play Singleplayer and have even tried hosting my server, but I keep getting this error message. Can someone please help? It would be greatly appreciated, I really wanna play with my spicy new additions.

Based off of a similar error I got from copying the preview file from \clientmods to \mods and the paths you've specified, do you have the "preview" folder in your \mods path in the root directory of the game? If so try removing it if you're still having this problem.

If it is a modpack with multiple mods inside make sure there is a modpack.txt file. If this is the case you will usually get
ERROR[Main]: cannot open preview:initlua: No such file or directory.

are you sure that file example.lua is there ? CHECK it !
