The language files need to be updated when updating the plugin from a version before 2.4.1. You can either add a variable called '%price%' in front or after the currency symbol in the currencysymbol message or remove the language file when no changes are made so it will regenerate a new one when the plugin is loaded next time.

Added:

• You can now disable all commands inside any world you want. (The option for this is located inside the config.yml, config.yml will automaticly update!)
• Option in config to set the locale in which the prices are formatted. (See this link for the diffrence in formatting prices using a french locale: https://imgur.com/a/vFAmL2d)
• Variable inside the language files to place the currency symbol after or in front of the price. (See message 'currencysymbol' inside any language file for this)
• Command to sell all items in your hand. '/sellall hand'

Fixed:

• When a message is not found inside the language file you're using, the plugin would trow a error.
• Infinite looping error when the used language file is misconfigured.
• Choosing items in the buy/sell screen still allowed you to choose amounts over the max stack size of the item that caused illigal stacking pluguins to break/remove the illigal stack.
• /sreload would not reload the language file (If changes made in config)

Removed:

• Unnecessary event
