I guess this is because the plugin already uses the data.db file, and when another player is trying to execute a command it just can't because the file is busy

[oplexz]

Does this error occur consistently, or every now and then? Do you have any ideas on how to reproduce this problem?

This might be caused by several DB operations being performed at once (e.g. two players registering at the same time -- although, unless they did it with pinpoint accuracy, it's highly unlikely -- the DB operations take a very short span of time.)

[f1refa11]

Does this error occur consistently

Yes, it occurs very often, and this is the problem why almost all the players can't login.

Do you have any ideas on how to reproduce this problem?

Unfortunately, i have no idea how to reproduce this, as it happens randomly, all I know is that is happens when there's more than 1 player in the server. So i guess you should just try authorizing from different accounts until the error occurs.
