Problems uploading plugins (CAN ANYONE HELP?)

Can you please help me, I am trying to upload plugins to my server, by dropping them in the mods folder. However, when I boot up the server this is what it says in the console.

Can anyone help me please figure out what is wrong, and how to upload the plugins correctly. Thanks, I am using professionalzen as a host btw.

Thanks,

Max.

That is a very old build of Sponge you’re using. May I humbly recommend at least updating to the most recent version for Minecraft 1.8.9, which is 4.2.0-BETA-1762 - and (as the name implies) using a more recent revision of the API (4.2.0). Older SpongeForge downloads are available here.

It’s also important to provide information on what Forge build you are using, at least [EDIT: found it, 1722]. Complete crash logs are also a must, as it’s impossible to figure it all out from an incomplete log file. Use pastebin, or something like it, and include a link.

If you really want stability, I’d recommend you update to 1.10.2 (if possible) and use the most recent SpongeForge builds for that version. There’s a lot more work that has been done on the SpongeAPI and implementations since the 1.8.9 builds.

It’s precisely what @Inscrutable said. [quote=“Helpme, post:1, topic:17512”]

GameReloadEvent wasn’t added until I believe 4.2.0, which this plugin uses.
