Will this add buttons on my posts with multiple pages?

Hi Anton,

Please do not worry about your existing multi-page posts. ACP doesn't replace the <!–nextpages–> shortcodes, but it finds and uses those to generate advanced pagination buttons. For example you have a post with this content:

First subTitle – iPhone 5S

This Smartphone is a good smartphone, and again… This Smartphone is a good smartphone, and again… This Smartphone is a good smartphone, and again… This Smartphone is a good smartphone, and again… This Smartphone is a good smartphone, and again… This Smartphone is a good smartphone, and again… This Smartphone is a good smartphone, and again… This Smartphone is a good smartphone, and again… Then you have WordPress pagination shortcode <!–nextpage–>

Second subTitle – iPhone 4S

This Smartphone is a good smartphone too, and again… This Smartphone is a good smartphone too, and again… This Smartphone is a good smartphone too, and again… This Smartphone is a good smartphone too, and again… This Smartphone is a good smartphone too, and again… This Smartphone is a good smartphone too, and again… This Smartphone is a good smartphone too, and again… This Smartphone is a good smartphone, and again…

Ok, so this content will be parsed by Advanced Content Pagination functions automatically. The result will be advanced buttons like this:

For #1 Layout:

For #2 Layout:

For #3 Layout:

For #4 Layout:

For #5 Layout:

Perfect! Thank you Artyom.
