Warning

Just realized it only happens if I choose the thick box option. It works fine but
shows the error. If I choose any other options, it does not happen.

@simonmuenger i am not getting you with the thick box option. Can you please provide screenshot for better clarification?

Thanks

@simonmuenger Please comment on line for now and check, it should work fine. I will work on the fix in this next update.

Thanks

Sorry, I don’t understand this sentence: Please comment on line for now and check,?

Are you a developer?

I am not a professional developer. Using WordPress and a few plugins for some friends. But don’t worry I liked to add the option trough your plugin. But found some other way. Not quite as good but allright.
