Hello, I am fairly new to modding, and I've just been using Nexus to install my mods

I have now run into some problems and I need help because I am basically clueless

I have tried uninstalling the ghost mode mod but that didn't solve the problem.

Error [modghostmode]game\gameplay\effects\effects\skill\undyingskillcooldown.ws(3): Unable to parse value
Error [modghostmode]game\gameplay\effects\effects\skill\undyingskillimmortal.ws(3): Unable to parse value

Warning [content0]engine\environment.ws(30): Global native function 'EnableDebugOverlayFilter' was not exported from C++ code.

Have you tried posting on this particular mod page on the Nexus seeking help?
If it's the one I think it is - the author of that mod is pretty active and might be able to help you resolve the error
