SSO and social login integrations depend on your site and the third-party provider (Google, Facebook, a corporate identity system) agreeing on a set of technical details that both sides have to keep in sync — a changed API key, an expired app credential, a redirect URL that no longer matches — and when they drift apart, the failure usually shows up as a vague error on your side rather than a clear explanation of what changed.
Check the browser console for the specific error during a failed login attempt
Open your browser’s developer console (F12 or Cmd+Option+I) and attempt the SSO login again. A specific error referencing the provider (Google, Facebook, or similar) or a redirect mismatch tells us exactly which side of the connection broke, rather than guessing from a generic “login failed” message on the page itself.
SSO / social login integration errors
SSO or social login broken by a drifted API key or redirect URL — found and reconnected.
- Full backup taken before we start
- If we can’t fix it, you get your money back
- We never ask for your own password
This or something else?
| SSO or social login is failing with an error, on your site or from the provider | This fix covers it |
| You want SSO set up for the first time, not fixed | A related but more involved initial integration task |
| The login page itself loops back after a successful attempt, unrelated to a third-party provider | Login redirect loop fix, a different issue |
| Users can log in via SSO but end up with the wrong role or missing access | User role & capability repair, a downstream issue from a working login |
What you are seeing
- An error during login referencing the SSO or social login provider directly
- The login button or flow simply not completing, with no clear error
- The issue possibly starting suddenly, without any change made on your own site
- A mismatch or redirect error specifically mentioned in the failure
Common causes
- An API key or app credential with the provider expiring or being revoked
- A redirect URL configured on the provider’s side no longer matching your site’s actual URL
- A plugin update changing how the integration authenticates, out of sync with the provider’s current requirements
- The third-party provider changing their own API or authentication requirements independently
- SSL or domain changes on your site invalidating a previously working redirect configuration
What we do
- Reproduce the failure and identify the specific error from the browser console
- Check current API keys, credentials, and redirect URLs against what the provider now expects
- Correct any mismatch between your site’s configuration and the provider’s current settings
- Test a full login attempt end to end to confirm it now completes
- Verify the resulting user account and role are correct after a successful login
- Document what changed, for reference if it happens again
What is included
- The specific cause of the SSO or social login failure identified and corrected
- A tested, confirmed working login flow end to end
- Verification of correct account and role assignment after login
- A written note on what changed and why
Not included
- Setting up SSO or social login for the first time, a separate, more involved task
- Resolving an issue on the third-party provider’s own systems, outside anyone’s direct control
- Broader user role configuration beyond confirming correct assignment
- Ongoing monitoring for future provider-side changes
Questions about this fix
Why would this break without me changing anything on my own site?
Third-party providers periodically change their own API requirements, security policies, or credential expiration rules independently, which can break a previously working integration with no action on your part at all.
Is this something I could fix myself by just re-entering my API keys?
Sometimes, if the credentials themselves simply expired — but if the cause is a redirect URL mismatch or a provider-side policy change, re-entering the same keys won't resolve it.
Will users who already have accounts be affected once this is fixed?
No, fixing the login flow doesn't affect existing accounts or their data — it restores the ability to authenticate, which existing accounts benefit from immediately once working again.
Could a plugin update have caused this even though the plugin still says it works?
Yes, a plugin can update successfully in a general sense while still creating a specific incompatibility with your provider's exact current configuration, which isn't always caught by the plugin's own testing.
How likely is this to happen again in future?
It's a genuine, ongoing risk with any third-party integration, since it depends on both sides staying in sync — not something a one-time fix eliminates permanently.

If this is the second time this year
A bad update breaking the site is a symptom of updates not being tested first. Care plans run every update on a staging clone before it reaches your live site, which is the actual fix for this happening again.
Your access, your rules
Create a separate admin account for us and delete it when we are done. For anything else, we get in touch and agree a method — never a form field on this site, never by reply to an email.
We back up first, always
Before anything is touched we take a full backup and keep it for 30 days. If a fix goes wrong, we put the site back exactly as it was.
If it is not what you bought
If the problem turns out smaller than what you ordered, we refund the difference. If it is bigger, we stop and send a quote before doing any extra work.
If we cannot fix it
You get back what we received. Diagnosis is on us — you only pay when the problem is actually solved. The payment processor takes its fee before the money reaches us, so we never hold it and it is not ours to return. That is true here as everywhere else.
If it comes back
Reply within seven days of delivery and we put it back on the bench at no cost. The fix is not finished until it holds.
What we are responsible for
If something goes wrong with a fix, our responsibility is limited to what you paid for it. We take a full backup first so mistakes can be undone, and we tell you before doing anything outside what you bought.
