Hello!
I need help updating this skyblock plugin.
This plugin is NOT made by me but here is it.
Here is the error im getting in the console:
Server thread/CRITICAL]: TypeError: "Argument 1 passed to SkyBlock\generator\SkyBlockGeneratorManager::__construct() must be an instance of SkyBlock\SkyBlock\SkyBlock, instance of SkyBlock\Main given, called in C:\Users\Administrator\Desktop\Cosmic Network\plugins\SkyBlock-0.1.8\src\SkyBlock\Main.php on line 140" (EXCEPTION) in "plugins/SkyBlock-0.1.8/src/SkyBlock/generator/SkyBlockGeneratorManager" at line 23

Once again I didn't make this plugin and I'm just trying to make it work on my server since the looks WAYYYYY better than the Skyblock Giant Quartz made. I looked in the src so that's why I'm saying that this is way better.
Please help thx

 

Have you modifyed the src yourself? There is no Main file or class in the link you provided

 

Nope, I didn't even TOUCH the src. The link I provided you is the developer's GitHub, not mine

 

Then you should try using the src from github
