sorry for the delay to answer. I have changed the plugin to the previous version. You can check it.
I have checked the responsive styles and there are some issues in the header in a resolution with 992px of width. Those problems are due to the styles you have added in the file style.css.
And for example, in the section ‘The Rumba Kings’ in a resolution 767px the texts dissapear on the left due to the style ‘margin-left: -30px’ added in the page design.
Do you want I resolve those issues?
