I tried with plugman and server restarts, both don't fix.

[yapzhenyie]

are you sure you are using 1.10?

[yapzhenyie]

do not using plugman to reload gadgetsmenu plugin, other plugins will get errors.

i haven't add morphs skills, please wait for the next update.

[NagisaStreams]

I am using 1.11 right now. This has been an issue since 1.10 however. It says unsupported version sometimes...

[NagisaStreams]

Im happy to send a full console boot log or plugin list, its just im trying to set up the lobby for my server lol I used to use UltraCosmetics, but I found this plugin to be much greater :D

[yapzhenyie]

if you didn't use plugman reload, you still get errors?

[NagisaStreams]

Yeah
especialy Unsupported major.minor version 52.0

[NagisaStreams]

Ive tried using newest build, tried using old builds.. still nothing

[yapzhenyie]

i think you're using 1.7 java.

[NagisaStreams]

Ill check, but here is the problem i think

Saying it can't load

[NagisaStreams]

Seems I am. Ill restart server, I use server.pro thought it was java 8 lol

[yapzhenyie]

please use java 8 to run the plugin, because it doesn't support 1.7 java

[NagisaStreams]

Looks like it worked loading! Thanks for the help never would have noticed that lol it says successfully loaded, and btw Plugman works for reloading and such, just not loading I used to reload it all the time

[yapzhenyie]

okay
