CAA DNS records: control which CAs can issue your SSL
Understand CAA DNS records, check whether one blocks AutoSSL or your paid CA, and add correct CAA records in the cPanel Zone Editor without breaking renewals.
Check which SSL certificate is installed and when it expires
Verify an SSL certificate: view issuer, covered names and expiry in the browser, cPanel SSL/TLS Status and the command line, and test the full chain externally.
Fix an expired SSL certificate and renew it in time
Recover from an expired SSL certificate: find out why AutoSSL did not renew, re-run it, renew and reinstall a paid certificate and set up expiry monitoring.
Fix an incomplete SSL certificate chain (missing CA bundle)
Fix "incomplete chain" and untrusted certificate errors on phones and apps by installing the correct intermediate CA bundle in cPanel, WHM, Plesk or DirectAdmin.
Fix mixed content warnings after switching to HTTPS
Find and fix mixed content on an HTTPS site: locate insecure http:// images, scripts and styles, update WordPress URLs, theme files and add an upgrade header.
Fix SSL certificate warnings in email clients
Stop certificate warnings in Outlook, Apple Mail and phones: use the correct mail server name, check AutoSSL covers mail subdomains, and pick the right ports and encryption.
Force HTTPS in WordPress the right way
Move WordPress fully to HTTPS: update the site addresses, redirect HTTP in cPanel or .htaccess, secure the admin, fix mixed content and avoid redirect loops.
Free AutoSSL or a paid SSL certificate: which do you need?
Compare MdmHost's free AutoSSL certificates with paid SSL: security, trust, validity, warranty and effort, plus clear cases where a paid certificate is worth it.
Generate, view and delete a CSR in cPanel for a paid SSL certificate
Create a private key and Certificate Signing Request (CSR) in cPanel SSL/TLS, copy it to your certificate authority, retrieve it later and remove old CSRs.
Get and install a wildcard SSL certificate
Secure all subdomains with a wildcard SSL certificate: when you need one, DNS validation, generating the CSR, installing it in cPanel and its limits.
Include or exclude domains from AutoSSL in cPanel
Control which domains and subdomains get free AutoSSL certificates in cPanel, exclude names that do not point to the server, and run a new check on demand.
Install a paid SSL certificate in DirectAdmin
Install a commercial SSL certificate in DirectAdmin: create the key and CSR, paste the certificate and CA root bundle, enable SSL for the domain and force HTTPS.
Install a paid SSL certificate in Plesk
Install a purchased SSL certificate in Plesk: create a CSR, upload the certificate and CA bundle, assign it to the domain and redirect visitors to HTTPS.
Install an SSL certificate on a domain in WHM
Install a paid SSL certificate for any account's domain from WHM: paste the certificate, private key and CA bundle, use autofill and verify the chain afterwards.
Redirect www and non-www to one HTTPS address
Make every version of your domain land on one canonical HTTPS address: certificate coverage for both names, .htaccess rules, WordPress settings and testing all four variants.
Self-signed SSL certificates in cPanel: when and how to use them
Understand self-signed SSL certificates in cPanel: why browsers warn about them, when they are acceptable, how to generate one and how to replace it with a trusted AutoSSL certificate.
SSL certificate types explained: DV, OV, EV, wildcard and multi-domain
Understand SSL certificate types: domain validated, organisation validated and extended validation, plus wildcard and multi-domain (SAN) certificates and when to use each.
SSL, TLS and HTTPS explained: how website encryption works
What SSL/TLS certificates are, how the HTTPS handshake protects visitors, the types of certificates (DV, OV, EV, wildcard), how validation works and why every site needs it.
