[13:07:34 ERROR]: #!#! Something went horribly wrong with Skript.
[13:07:34 ERROR]: #!#! This issue is NOT your fault! You probably can't fix it yourself, either.
[13:07:34 ERROR]: #!#! Your Minecraft version or server software appears to be unsupported by Skript (bensku's version).
[13:07:34 ERROR]: #!#! Currently only supported servers are Spigot and its forks for Minecraft 1.9 or newer.
[13:07:34 ERROR]: #!#! Other versions might work, but since you're getting this error message something is NOT working,
[13:07:34 ERROR]: #!#! nor it will work, unless you switch to supported platform.
