A free malware scan only sees what a visitor sees. A live run of 69 well-known sites through Sucuri SiteCheck shows what it finds, the false alarms and blocked scans, and the server-side checks that fill the gap.
You can read a WordPress theme in ten seconds and a few plugins in a minute. A live check of 29 real sites and this site’s own 24 plugins shows how much a theme and plugin detector can see.
A security headers check reads six response headers. A live survey of 63 well-known sites shows which ones are common, what WordPress and the host send by default, and a safe order for adding them.
Four free checks can name a site’s host: IP owner, nameservers, headers and page source. A live survey of 69 well-known sites shows which ones work and why a CDN hides the host on seven sites in ten.
Yes, but extra MX records are for one provider’s redundancy, not for running two. How priority and failover work under RFC 5321, what 69 real domains publish, and how to switch providers without losing mail.
Shopify does not host mailboxes. What it does give you for business email, the sender-address rewrite that catches new stores, and what 29 well-known Shopify stores run on their own domains.
Blacklists list sending IPs and domains, not mailboxes. How to check one by hand, a live test showing Spamhaus returns a false ‘clean’ through some public resolvers, and what to do if you are listed.
Four ways to test email deliverability on a WordPress site, what each one can and cannot prove, and real SPF, DKIM and DMARC results from 63 received messages across two site mailboxes.
Four ways to restore a WordPress site from a backup: host panel, plugin, FTP with phpMyAdmin, and WP-CLI. See which one fits, why files and database must match, and what to check afterwards.
Free Gmail stops at 500 messages a day and Google Workspace at 2,000. See how many WooCommerce orders that covers, what the 550 5.4.5 error means, and when your host is the tighter limit.
