You're running 1.10, but you've installed a coremod that was built for 1.7.10 or earlier.

 

Why are you using 1.10? Ideally you should update to 1.12.2, but failing that at least use 1.10.2. There's no reason not to use the latest bugfix release within a major version.

[halppls]

Just updated to 1.10.2 and had the same thing happen and the reason im not using 1.12.2 is that not all the mods i have are updated to 1.12.2

[halppls]

Anyway to tell which one is causing the error?

[halppls]

I know which mods i have installed however this happens everytime i try and add any of the mods
