HI, Sydney Pro was working fine. Had to create a new domain. So, created new domain, installed WordPress then used WordPress import/export feature to bring pages from old site to new site. Then installed themes,plugins etc.
WordPress will not allow me to use Sydney Pro as the default editor, SiteOrigin Page Builder is my default page editor but I have no option to pick anything when making a new page or trying to modify an existing page.
I have a couple of other sites using Sydney and it works amazingly.
