Totally broken

Still charging my client full amount ($552/year) and the plugin is so neglected that it has been fully deactivated in the WordPress marketplace.

Thank you Olark!

Finally, will have something stable! Thank you to the always awesome team at Olark. Just one thing to fix on my side, and the only reason I didn’t give it 5 stars, how can I make it multilingual now?
