Manual eCommerce Site Setup On SiteGround: Week 2

Changed file permissions on WP-CONFIG.PHP.
Deleted Yoast SEO plugin & installed All-In-One SEO Pack plugin. The reason for the change was that the creators have crippled the latest version of Yoast SEO — it no longer allows the site owner to NOINDEX specific pages in its XML sitemap. Since the Cancelled Transaction, Checkout, and Thank You pages should not be indexed, Yoast SEO was unsuitable for this site’s needs.
Monitored page indexing on Google. Indexed pages reached 7 on the first evening, then fell to 2 a couple of days later (probably due to delayed propagation across Google’s servers). As of today, the number of indexed pages was 8.
Plugin mistakenly was blocking Bingbot. Contacted plugin support & problem was resolved.
Submenus on handheld devices were not displaying due to theme update. Was unable to use CSS to target the issue. Therefore, created a second menu for use on handheld devices only.
Floated the hamburger menu on handheld to the left.
Media attachment pages on Ancient Greek Keyboard were being indexed by Google, which is apparently bad for SEO. Changed Media Attachment settings in All-In-One SEO plugin, then set up redirects for media attachments with code in Child Theme > FUNCTIONS.PHP.
