Fix my SSL error

How It Works

Fix WordPress SSL certificate errors

Share the browser warning

Screenshot the error and note whether it affects the whole site or specific pages.

Audit cert and URLs

We check certificate expiry, WordPress URLs, and mixed content, then confirm the fix price.

Repair HTTPS end to end

Renew or reinstall the certificate, update URLs, and fix mixed content so checkout and forms load securely.

Common WordPress SSL certificate errors

SSL errors range from expired certificates visitors see in their browser to subtle mixed-content warnings that break checkout or login. WordPress sites need both a valid certificate and correct internal URL configuration.

Migrating to HTTPS without updating WordPress settings is one of the most frequent causes of post-SSL breakage.

Expired or not-yet-valid SSL certificate
Certificate issued for wrong domain or subdomain
Mixed HTTP and HTTPS content on pages
Incorrect WordPress site URL after HTTPS migration
CDN or reverse proxy SSL misconfiguration

Fixing SSL beyond installing a certificate

Installing a certificate is only half the job. WordPress siteurl and home URLs must use https://, hardcoded links in content and widgets need updating, and plugins loading external scripts over HTTP must be reconfigured.

Developers use search-replace tools carefully on serialised data and verify checkout, forms, and admin login over HTTPS.

BugShield SSL certificate fixes

SSL and mixed-content fixes start from £49.99 with a confirmed quote. We resolve certificate issues, update WordPress URL settings, and verify browsers show a secure padlock on key pages.

For ongoing monitoring of certificate expiry and uptime, Shield Light includes full monitoring from £99/month.

Certificate error or mixed content?

A certificate problem affects the secure connection itself. Mixed content means the page is secure but still loads one or more resources over HTTP. Each needs a different fix.

Check every domain in use

The main domain, www version, subdomains, CDN hostname, and redirected domains may need separate coverage or configuration. We identify which hostname produces the warning.

Test secure journeys after the fix

HTTPS redirects, login sessions, forms, account pages, and checkout should work without loops or warnings. We also confirm that WordPress generates secure URLs consistently.

Evidence of the work

How BugShield verifies the result.

Emergency work starts by preserving useful evidence and defining what safe recovery means. The site is checked beyond the first visible symptom before normal use resumes.

See how an unavailable WordPress site was recovered

01

Build an incident timeline

Record when the problem began, what visitors see, recent changes, and whether sales, access, data, or security are affected.
02

Check every affected layer

Review the relevant logs, files, database records, users, credentials, DNS, and hosting state instead of treating the visible symptom in isolation.
03

Confirm a safe recovery

Test the public site, wp-admin, and the important journey that failed, then verify that warnings, redirects, malware behaviour, or server errors are gone.

FAQ

WordPress SSL certificate error FAQs

Can BugShield install a free SSL certificate?

We configure Let's Encrypt or your host's free SSL where supported. The fix labour is quoted upfront, typically from £49.99.

Will fixing SSL break my site?

We test redirects and key pages before handover. Staging is used when available to avoid checkout disruption.

Do maintenance plans include SSL monitoring?

Shield Light and Shield Pro include monitoring that alerts you to downtime and certificate issues before visitors notice.

Why does my browser say my WordPress SSL certificate is not valid?

The certificate may have expired, been issued for the wrong domain, or not be installed correctly on your server. Mixed HTTP and HTTPS content can also trigger warnings.

Can WordPress cause SSL errors after enabling HTTPS?

WordPress itself does not issue certificates, but incorrect site URL settings, hardcoded http:// links, and plugins loading insecure assets cause mixed-content warnings.

Do I need to buy an SSL certificate?

Most UK hosts include free Let's Encrypt certificates. If yours has expired or was never installed, we work with your host or CDN to renew and configure it.

Will fixing SSL help my WordPress SEO?

Yes. Google treats HTTPS as a ranking signal and browsers warn visitors on insecure sites. Fixing certificate and mixed-content issues restores trust and search visibility.

Can an SSL error affect checkout or login?

Yes. Secure cookies, payment scripts, redirects, and browser trust can fail when HTTPS is incomplete or the certificate does not match the domain.

Why does the SSL warning appear on only one page?

That page may load an image, script, form, or embedded item over HTTP. It can also use a different hostname not covered by the certificate.

How do you verify an SSL certificate repair?

We check the certificate chain and hostname, test redirects, and review key pages for insecure resources. Login, forms, and checkout are tested where relevant.
