If you can give me your admin console access i think i can fix your problem. if you want me to fix, please contact me via PM and send me the details.
You can let me help you to check your website? because everyone's website may have some difference and third-party plugin may effect, or maybe the core version differences.
I don't have instructions because i don't know what cause the problem. I have many clients, but they have no problems like this. Would you please allow me do my job to check the problem? i think just some css problem.
I'm pleased to say everything is working very well and I'm happy. As with all themes there are differences, and things may need slight adjustments through css in Admin panel. Daniel helped with all. Great plugin. Thanks Daniel
