When I reload a server and login the server, ScoreBoardStats works, but when I relogin, ScoreBoardStats dissapears. If I try login the server with another version of Minecraft or login after some minutes\hours of my being away of the game, ScoreBoardStats doesnt work. I need to reload the server to make ScoreBoardStats works again, but if I relogin, it dissapears again. I need set "compatibilityMode: false" to make it works after relogin, but another plugins dont work if I set it. How can I fix it?
Sorry for my English.

Version: spigot 1.7.10
No error in console
Plugin list: AuthMe AutoMessage ChatGuard ChatManager ChestCommands ClearLag ClearWorld ColoredTags CustomJoinItems Essentials HealthBar Marriage MineResetLite MultiMOTD NoCheatPlus PermissionsEx PluginMetrics ScoreboardStats SmokeTrail Updater UralClans Vault WGFix WorldBorder WorldEdit WorldGuard iConomy mcjobs update

Looks like I found the issue in #117

ScoreboardStats conflicts with ColoredTags. You have to activate compatibility and install ProtocolLib.

I have had this plugin, but i haven`t mentioned about it.

So you already have this plugin installed?

Yes I have

Then activate compatibilityMode in ScoreboardStats. You wrote that you deactivated it.

When I activate it, ScoreBoardStats dissapears after relogin

Could you post your log please.

It means that another plugin is overriding the sidebar scoreboard.

Thank for your help. I will be looking for plugin which overrids the sidebar scoreboard.
