FAQ
How quickly can you fix a WordPress critical error?
Simple issues may be resolved within a few hours, but complex PHP, plugin, or server errors can take longer. Delivery depends on the issue and selected package.
What causes the WordPress critical error message?
Common causes include PHP fatal errors, plugin conflicts, theme issues, memory limits, and incompatible updates. I will investigate the error logs to identify the likely cause.
Do you need my WordPress login or hosting access?
Most issues require temporary WordPress admin access. For PHP fatal errors, database problems, or server-related issues, hosting or SFTP access may also be needed.
Can you fix database connection errors?
Yes. I can troubleshoot database credentials, configuration, server connectivity, and related WordPress database errors. Some fixes may require hosting provider assistance.
Do you offer support after completing the fix?
Yes. I can help with issues directly related to the completed fix within the agreed revision scope. New or unrelated issues may require a separate order.
Can you fix Elementor and mobile responsive issues?
Yes. I can troubleshoot Elementor editor errors, broken layouts, CSS conflicts, and mobile responsiveness problems in WordPress websites.
Can you remove malware or fix a hacked WordPress website?
I can review suspicious behavior and help assess the issue. Malware removal, full security cleanup, and recovery require a separate scope and quote.
Can you fix WooCommerce checkout or payment gateway issues?
Yes. I can investigate WooCommerce cart, checkout, payment gateway, product, and order-related errors. Third-party provider issues may require their support.
Can you fix WordPress SMTP and email delivery issues?
Yes. I can troubleshoot SMTP settings, email authentication, and WordPress email configuration. Final delivery also depends on your hosting and email provider.
Can you fix WordPress 404 errors and permalink issues?
Yes. I can troubleshoot broken permalinks, 404 errors, rewrite rules, and common redirect problems. Server-level issues may require hosting access.
