Hey Buddy,
I have checked both Plugin GIT URL and Notices which you are getting. It's because of compatibility of current plugin with PHP version you are using.
I can do this within couple of hours and upgrade the component files to work with Future PHP versions.
I'll need Joomla admin details and FTP. So I can start my work and show you the progress.
Having 5+ years of experience in Joomla Development.
Thanks,
