This is byfar the most stable version of EconomyShopGUI that works on multiple versions of minecraft, this is why I decided to make it a non beta version.
If you still found a bug, join our discord server and we will try to fix it.

Fixed:

• Debug message when a material is not supported.
• Error when using newly added materials on older MC versions. (This fixes the plugin creating errors on startup and not enabling)
• When a config (shops.yml, sections.yml or any language file) is mis-configured it won't mess up your shop anymore with example sticks. (The plugin will disable itself if a config is mis-configured to prevent errors in the future or players that can steal items from shop)
• Option 'name-config' is no longer used in the sections.yml file. This will fix some shop sections that wouldn't open if the name inside option 'name-config' didn't match its parent name.

Added:

• You can now add empty spots inside a shop section by specifing the material as 'AIR' inside the shops.yml config.

Removed:

• Debug message that outputs the path of the item in console when using '/sellall' command.
