Emailed Author: There are issues with your plugin code.
Please read this ENTIRE email, address all listed issues, and reply to this email with your corrected code attached. It is required for you to read and reply to these emails, and failure to do so will result in significant delays with your plugin being accepted.
Also please remember in addition to code quality, security and functionality, we require all plugins adhere to our guidelines. If you have not yet, please read them:
## Using Fancybox 2.0
It’s required that all code be compatible with GPL to be included in our directory.
FancyBox v2 is not GPL compatible, as it has been licensed Creative Commons.
You may use FancyBox v1 and v3, but not v2.
If you cannot alter the code, we suggest you find alternate code that is GPL compatible and use that instead. For more information on what types of licenses are compatible with GPL, please review the following links:
## Including full vendor folders
Your plugin includes the vendor folders (like Bower or Node folders). You really don’t need to do this. The entire library isn’t going to be used by your users, and having all those files included is just extra weight to a plugin. Please remove them and ONLY include the files you need.
Please make sure you’ve addressed ALL issues brought up in this email. When you’ve corrected your code, reply to this email with the updated code attached as a zip, or provide a link to the new code for us to review. If you have questions, concerns, or need clarification, please reply to this email and just ask us.
(While we have tried to make this review as exhaustive as possible we, like you, are humans and may have missed things. As such, we will re-review the ENTIRE plugin when you send it back to us. We appreciate your patience and understanding in this.)
