Permalinks okay some pages but 404 error on others

Problem fixed YAY. I had to edit the permalinks on the three main pages that were generating the server 404s. In other words, I changed about to about-client-name, changed services to services-page, and changed contact to contact-us. The 404 behavior went away. This also fixed the subordinate services pages and the subordinate about page.

Hata!: SQLSTATE[HY000] [1045] Access denied for user 'divattrend_liink'@'localhost' (using password: YES)
