As a follow-up, I’ve installed Zen Cart using Softaculous and it’s own database, just to get ZC installed. Again, I know the DB for WP and ZC have to be the same. Now that these 2 DBs exist, is it possible, using MyPHPAdmin, to copy/move/import/some-other-method the tables in the ZC database into the WP database? Can I somehow merge the two? Finally, even if I could merge the two DBs in some way, would this get Zen4WP to work?
