Problem/Bug [/AR CHECK] An Internal Error occured

Hi all, I have a problem with /ar check and /lolmewnstats commands

Firstly, when I stop server and re-start I get error and all stats reset except move/join and playtime.

I saw this message all time in log file;
[15:17:31] [Craft Scheduler Thread - 8/ERROR]: [Stats] Couldn't retrieve connection from pool, erroring

I guess it was because of not connect to mysql and I tried to connect mysql with cmd with same password and username and I connected;



Also I checked my database and I saw there is a table's, which created by stats plug-in;


And another problem is AUTORANK. When I use /ar check I get, "An internal error occured while attempting to perform this command." error. And the log;

Code:

[15:25:50] [Server thread/INFO]: xwerswoodx issued server command: /ar check

Thanks for everyone.

 

I know this is flooding but I want to give my solution.

All the problem was PermissionsEx because autorank 3.7.2 doesn't work with PermissionsEx, when I change it to permissionbukkit 2.3, it worked for me.

Also for stats, there is a problem on Stats 3.0.2 plug-in, but it compatible with stats 3.7.2.

Edit: Last permissionsEx version supported.
