Website repair after a migration, when the site or email is down
If your site, shop or email stopped working after a move, it's worth finding the cause quickly. Post-migration errors can affect customers, sales, forms and Google visibility.
Problems covered by post-migration website repair
Post-migration errors have various causes — from configuration mismatches and wrong URLs to DNS and SSL certificate problems. We diagnose the specific cause and fix it.
White screen
A blank white page often means a PHP error, a plugin problem or a wp-config.php with wrong database details.
Database connection error
Wrong database credentials, a missing database or a wrong host name after the migration.
Broken forms
Forms don't send messages after a hosting change — an SMTP configuration problem or a send block.
SSL problems
The SSL certificate has expired, isn't installed on the new hosting or isn't assigned to the domain.
DNS problem
The domain still points to the old hosting or the DNS records are misconfigured.
No email
After a hosting change email stopped working — accounts are missing, messages are lost or MX records are wrong.
404 errors
Subpages return 404 after the migration — a problem with .htaccess or the redirect configuration.
Redirect problems
Redirect loops, wrong URLs or broken internal links after a domain or hosting change.
The shop won't take orders
WooCommerce or PrestaShop errors — the cart doesn't work, payments fail or transactional emails don't arrive.
The WordPress panel doesn't work
No access to /wp-admin — a wrong URL, an .htaccess problem or a corrupted database.
Old version of the site
The domain shows the old site — a DNS propagation issue or hosting-side cache.
The site is slow after the migration
Slower new hosting, a missing cache plugin or a sub-optimal PHP-FPM configuration.

How repair after a failed migration works
Quick diagnosis
We analyse the symptoms, error logs and server configuration to pinpoint the cause.
Securing the current state
Before making changes we back up the current state — so we can return to the starting point if needed.
Identifying and fixing the error
We fix the specific cause of the problem — we don't experiment on production without a plan.
Functional testing
We check the site, form, email, shop and SSL certificate after applying the fixes.
Recommendations for the future
We tell you what caused the problem and how to avoid similar situations in future changes.
