Hire Troubleshooting Developers

WordPress troubleshooting is one of the most in-demand skills on Codeable. Sites break for many reasons – plugin conflicts, theme incompatibilities, hosting changes, failed updates, PHP version mismatches, database corruption, hacking, caching conflicts, and more. The skill of troubleshooting is not knowing the answer before looking – it is having a systematic method for isolating the cause and applying the correct fix.

Professional WordPress troubleshooters follow a consistent diagnostic methodology: reproduce the problem reliably, identify what changed before the problem appeared, isolate the cause by eliminating variables (disabling plugins one by one, switching to a default theme, testing with different user roles), find the specific cause, and apply a fix that addresses the root cause rather than masking symptoms.

Common WordPress problems requiring troubleshooting expertise include: the white screen of death (PHP fatal error), plugin conflicts that break specific functionality, sites that break after WordPress or plugin updates, caching problems causing stale content or incorrect displays, email delivery failures, SSL and HTTPS issues, login and redirect loops, and database connection errors. Our guides on fixing the white screen of death and finding and fixing plugin conflicts cover the most common scenarios in detail. WordPress White Screen Of Death Fix.

WordPress troubleshooting engagements typically cover:

• Site broken after an update – a WordPress core, theme, or plugin update caused a white screen, broken layout, or lost functionality. Identify which update caused the problem and apply a compatible fix.
• Plugin conflict diagnosis – two plugins are interfering with each other, causing broken functionality on specific pages or across the site. Identify which plugins conflict and find the resolution.
• Site not sending emails – WordPress emails (contact forms, WooCommerce orders, user registration) are not arriving. Diagnose whether the problem is server-level email configuration, plugin misconfiguration, or spam filtering.
• Slow site diagnosis – the site is slow but the cause is not obvious from front-end tools. Use server-side tools to identify the bottleneck.
• Login issues – redirect loops, session conflicts, or authentication failures preventing admin access.
• Database errors – “Error establishing a database connection” and related database connectivity problems.

Good troubleshooters have a systematic method and can explain their diagnostic process. Ask how they approach a problem they have not seen before. The answer should describe a method – reproducing the problem, identifying recent changes, isolating variables, using diagnostic tools – not just listing things they might try.

Ask about their experience with WordPress debug tools: WP_DEBUG for PHP errors, Query Monitor for database and hook inspection, browser developer tools for JavaScript errors and network requests, and server error logs. A troubleshooter who uses these tools systematically diagnoses problems faster than one who relies on guesswork.

Ask about their communication during troubleshooting. Troubleshooting on a production site affects real users. A developer who communicates clearly about what they are testing, what they have found, and what they plan to do next keeps the client informed and prevents surprises – like discovering the developer disabled all plugins on a live site.

The most common WordPress problems and their diagnostic starting points: How To Find Fix WordPress Plugin Conflicts.

• White screen of death – enable WP_DEBUG in wp-config.php to reveal the PHP error. Check the server error log. Disable plugins and switch to a default theme to isolate the cause.
• Site broken after update – roll back the most recent update on staging to confirm it is the cause. Check the plugin or theme changelog for known issues. Contact the plugin developer if no solution is available.
• Plugin conflict – disable all plugins, confirm the site works, then re-enable plugins one by one until the problem reappears. The last enabled plugin is the conflicting one or reveals the conflict with another active plugin.
• Emails not sending – check wp-mail.php is functioning with a test plugin. Configure an SMTP plugin to bypass WordPress’s default mail function. Check server spam policies and sending reputation.
• Login redirect loop – clear all cookies and browser cache. Check WordPress home and siteurl settings in the database. Disable security plugins that may be affecting login redirects.

Ongoing WordPress maintenance prevents many troubleshooting situations. Keeping plugins, themes, and WordPress core updated on a schedule, testing updates on staging before applying to production, and maintaining current backups are the foundations of a stable WordPress site that rarely needs emergency troubleshooting.

Sites without a maintenance routine accumulate technical debt – outdated plugins, incompatible PHP versions, unconsolidated customisations – that makes future troubleshooting harder and breakages more likely.

When posting a troubleshooting project on Codeable, describe the problem as specifically as possible: what is happening, what should be happening, what error messages appear, and what changed before the problem appeared. Include the WordPress version, active theme, and any plugins you suspect are involved. The more detail you provide, the faster a troubleshooter can diagnose.

For urgent problems affecting a live site, say so clearly. Many Codeable developers prioritise urgent requests and can begin immediately.
