@t-p, thank you for the resource links. I went over them and found that the permalinks were already set up correctly, and installed the premium theme we will be using to redesign the site. However, the importer still will not accept the export file from their wordpress.com site.

Please contact WordPress.com support at https://support.wordpress.com/ ask them why

the importer will not accept the export file from their wordpress.com site.

Also try contacting your hosting provider in case it’s a server level problem.

Thank you, I’ll contact WordPress support and see what they say first. I’ve just learned that my client’s don’t want to import their entire site, but will import their existing posts and probably their subscribers once we have the rest of the site completed. I really appreciate your help, @t-p, thanks and have a great Fourth of July.
