And the error says it all: Code (Text): [WARNING] Plugin SimpleHolograms v1.0.0 does not specify an api-version. [ERROR] Could not load 'plugins/SH.jar' in folder 'plugins' org.bukkit.plugin.InvalidPluginException: java.lang.NoClassDefFoundError: net.minecraft.server.v1_7_R1.Packet at org.bukkit.plugin.java.JavaPluginLoader.loadPlugin(JavaPluginLoader.java:139) ~[spigot-1.15.1.jar:git-Spigot-037559e-661bebc] The error is saying you are trying to load a plugin written for 1.7.x on your 1.15.1 server. A simple search of SimpleHolograms shows that said plugin has not been updated since 2014... That about sums that up for ya. ALSO: Code (Text): ********************************************** ** This WorldEdit version does not fully support your version of Bukkit. ** ** When working with blocks or undoing, chests will be empty, signs ** will be blank, and so on. There will be no support for entity ** and block property-related functions. ** ** Please see https://worldedit.enginehub.org/en/latest/faq/#bukkit-adapters **********************************************
Bruh can u atleast look at ShaneBee's reply? Bukkit.org clearly shows that Simple Holograms literally only has one version. 1.7.2. And you want him to update, code it for him, he'll be happy.
