Bug fixing and updates

[KLicheR]

Hi!,

Thanks for your interest in my plugin.

Unfortunately, I do not have all the time I would like to improve it. I work in a web shop and improve it when I work on projects that need it. It's one of the reason why my plugin is not on Wordpress.org yet but on GitHub. If people want to help with it, I will be happy to check pull request.

I will probably work on it again soon but can't make any promises but I assure you that this is not a "dead" project.
