I opened the plugin translation projects for begin translating the strings of Stable and Development projects, but a got an error notice saying: “This plugin is not properly prepared for localization”.

I looked inside the code I found the cause of this: you’re already have well done formatted the strings, but you’re using a different text domain of your plugin slug of directory.

The text domain that you’re using is “gwptb”, but your plugin slug in WordPress plugin directory is “green-wp0-telegram-bot-by-teplitsa”. You must to change it to the last one if you want WordPress generate the project with the strings to translate your plugin to another languages.

Hope this helps you to improve your plugin and reach another users ??
