Known Fix:

 

[Solarstrike]

I have no idea what you're talking about.
(and by the way, I don't think that's an error)

 

[Axis113]

Is the pack properly installed (are all the mods in the "mods" folder)? If so are both the server and client on the same version?

 

[Relaxel]

Those are simple mod rejections, meaning that you either have a different version of FTB Infinity installed than the server, or your mods folder is somehow different to the server´s.
