Sydney Pro seems to break pagination.
I’ve got a couple plugins that create pages with links to previous and next, or that use collapsible content, these don’t work on Sydney Pro - the page just scrolls a little instead of loading the intended content.
These plugins work fine on other themes.
What controls the on screen pagination?
Thank you for reporting.
Could you please mention what plugins they are?
Could you please share your site URL here so I can have a closer look?
