No tabs show up with and no longer able to advance to the next page

This plugin doesn't seem to work at all.

It doesn't replace pagination shortcode and generate advanced pagination buttons (which is why I paid for the Pro Version).

I have the Pagnation Buttons Layout set to 'tabbed'

All that happens is that my page only shows the first page with no option to advance to the next page.

My 'next page' codes were placed in the "Text" tab not "visual".

I haven't experimented with inserting the plugins short codes because there is no information given on what those codes are.

Any help would be appreciated

Thanks
