That did seem to fix the 503 service errors. The PowerCMS logs in, however "update" content throws "syntax error in SQL". Left sidebar + content makes new entry X deletes entry-- no prob, update on new entry throws sql error.
The rendered page called from url does not call the content from the database. BUT, we're ALMOST THERE!!!!
uncommented pages that use powercms but not getting content:
https://preferred-cell-systems.com/Cameo96_TEST.php (also contains sqli queries from products database)
https://preferred-cell-systems.com/HALO-page_TEST.php (contains only content from powercms database)
