After I finished adding the product, he told me that an error had occurred

Add an option, in config.yml, to define the limit number that the person has to buy the item per purchase screen! Because it is very bad when selecting, with the standard limit, when the person only wants to buy 2, for example, and can only select 0 or 6.

Example in config.yml:
buy-limit: 128

Hi I try to sell a item and it doesn't allow me to do so unfortunately. Every time I try to sell a item the shop interface states I have nothing to sell. I was wondering is there a fix to this issue ?

Thank you so much for creating such a nice plugin!
Can you add new feature to this plugin? For example, you can only buy items. What if the command is also available for purchase? For example, if you buy a product, the custom command like "/effect %p 1 200 0 true" will be executed. Or you can put command like enchat command so you can make enchant shop too! (%p mean the player that buy it. For example, Minecrafter buy this command, then "/effect Minecrafter 1 200 0 true" will be executed.)
Then thank you very much!

When players with space in their names try to access the shop GUI, it prevents it by saying "unknown command". This is a major bug on my server, so please fix it ASAP. Thank you!

There is a serious bug!

When it arrives at the part of the item you want to sell, you click on the item you want to sell, throw it away while it is in transition, and it still considers the item to be in the inventory, but not in the inventory! So he just clicks to sell and doesn't take anything from his inventory, considering he did!

• The solution for this would be when the person finishes the sale, in the part in which they select how much they want to sell and click on the button, first take the item from the inventory and confirm that the item is really in the inventory, showing an error text if the item is not in the inventory, but if you confirm that it is in the inventory there you can hand over the money!

Can the plugin show how much it costs per item before selling it to the store?

In branch 'rewrite'

Hey!
If users get, say, a diamond, which on my server is sold for quite a bit, players can rename that diamond to diamond, then sell it, and make infinite cash.
Please do resolve this issue!
Thanks!
