After upgrading both WordPress and the underlying PHP version my blog immediately went down and now shows only “There has been a critical error on this website.” Nothing else renders—no dashboard access, no front-end pages, nothing. Debugging is currently turned off and I’d rather not experiment on a live site, so I need you to step in, switch on WP_DEBUG safely, read the resulting logs, trace the conflict and get the site loading normally again. Whether the culprit is a theme, a plugin or the new PHP version, I expect a clean explanation and permanent fix. Deliverables • Enable WordPress debugging without exposing sensitive data publicly • Pinpoint the exact cause of the critical error (plugin, theme or core/PHP incompatibility) • Apply or recommend the necessary patch, update or configuration change • Confirm that the admin area and all public pages load correctly post-fix • Provide a brief summary of the steps taken so I can keep it on record Please work directly on the live server only if you’re confident; otherwise let me know and I can spin up a staging copy for you.

That "critical error" right after a WordPress and PHP upgrade almost always means a theme or plugin isn't compatible with the new PHP version and is throwing a fatal error—very fixable once we see the log. I'll safely enable WP_DEBUG with WP_DEBUG_LOG so errors write to a private log file rather than showing publicly, read the exact fatal error and the file it points to, then confirm the culprit by selectively deactivating plugins/switching theme via the file system. Once pinpointed, I'll apply the right fix—update or patch the offending plugin/theme, or adjust the PHP config—and verify both the admin dashboard and all front-end pages load cleanly. I'll leave debug switched back off and give you a short written summary for your records. Happy to work on staging if you prefer, but I'm confident doing this safely live. I can start right away.

Hi, I can tell this is the kind of failure that happens when one update quietly exposes another, usually a PHP incompatibility, plugin conflict, or theme hook breaking the whole stack. I’ve fixed many WordPress critical errors by safely enabling WP_DEBUG, reading the logs, isolating the exact cause, and restoring the site without guesswork. I’ll work carefully on the live server, or on staging if you prefer, and make sure the debug output stays private while I trace the issue. Once identified, I’ll apply the right patch, update, rollback, or configuration fix and verify both admin and frontend are loading normally. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. Looking forward to your reply so we can finalize the exact plan. Would you like me to inspect the live site directly, or should I wait for a staging copy first? Thanks, Asad

Hello, Your WordPress blog is down after a PHP upgrade, and the error log should reveal whether a plugin, theme or core file is causing the conflict. I recently debugged a similar critical error on a live WordPress site where PHP 8.2 broke a custom theme—fixed by rolling back one outdated plugin and updating another to its latest version. I’ll safely enable WP_DEBUG, read the logs to isolate the exact source of the failure, then apply the minimal patch—whether it’s a plugin update, a theme tweak or a PHP configuration change—before confirming the site loads again. The goal is restoring full admin access and front-end visibility without exposing debug information or causing further downtime. Let me know if you prefer I work directly on the live environment or if a staging copy is easier for you. Thanks, Lazar.
