Attempting to install Forge into my minecraft 1.2.5 to be used on a bukkit server. When I install forge on its own and try running the client I get this error:

This is the only mod I have on the client, removed the meta inf.

 

This shows up in the ModLog:

How big is your texture pack?

FML does not support 256+

So use 128-

Or add Optifine to the mix for full Texture support.

Yeah, I finally figured that out. Now my issue is getting this to work with bukkit. I'm trying to make it work with 1.2.5.5-0 and I get this when I run the server :

Press any key to continue . . .

 

...

You can't install Forge on bukkit, go look for CraftBukkit++ on MCPortCentral for a Forge/CraftBukkit build.

Yeah. I found that out as well. Now when I log in and try to move one of the items for the mod I'm doing it just kicks me out with a generic error.

 

No such thing as 'generic error' -.-

It does say generic error on the bukkit server side. I finally managed to get it to work with your suggestions and help thanks. Shame towny seems to not work with it. (gives errors and won't load towny)
