This is UNOFFICAL fork of Easy Invitation Codes Wordpress plugin https://wordpress.org/plugins/baw-invitation-codes/ I forked it and solved a couple of problems and php warnings. I use the plugin on of my client's site and it was so annoying that the proplem wasn't solved. So I decided to solve the problems and release my own version without ignoring the original author and the maker of the plugin.
Download the repo and upload the folder baw-invitation-codes to your wp-content/plugins/ folder via FTP
- All invitation codes are now UPPERCASE to avoid incosistency
- Fixed two PHP notices and warnings and one exception.
