Finding the actual cause when WordPress breaks.
Troubleshooting
A loopback is WordPress calling itself over HTTP. When it fails, cron, the editor's recovery features and the plugin editor stop working — and the cause is nearly always DNS, auth or a firewall.
Troubleshooting
Horizontal scrolling, tiny text and a broken menu each have a specific cause. Reproduce the problem in a device emulator, find the element that overflows, and fix the rule.
Troubleshooting
Scan with a crawler rather than a resident plugin, fix internal links at the source, and redirect only where a genuine equivalent exists. Deleting the link is often the right answer.
Troubleshooting
Corrupted tables produce missing content, failed saves and repair prompts. Back up first, then use WordPress's built-in repair, phpMyAdmin or the command line — in that order.
Troubleshooting
Cleaning malware is only half the job. Contain the site, replace core and extensions with clean copies, close the entry point, and rotate every credential before going public again.
Troubleshooting
A PHP upgrade breaks code that used removed syntax or relied on loose behaviour. Read the fatal error, identify the responsible plugin or theme, and roll back the version while you fix it.
Troubleshooting
The Site Editor needs a block theme, a reachable REST API and working JavaScript. Missing menu item, endless spinner and blank screen each point at a different one of the three.
Troubleshooting
A site rendering as plain text means the stylesheet request failed. Open the network tab, find the failing request, and fix the URL, the mixed-content block or the broken minified file.
Troubleshooting
Before touching WordPress, find out whether DNS resolves, the server answers and PHP runs. Each layer fails differently, and the browser message tells you which one to look at.
Troubleshooting
When pretty URLs return 404 but the homepage loads, the server is not routing requests into WordPress. Fix the rewrite layer instead of changing the permalink structure.
Troubleshooting
A missing menu is usually an unassigned location, a cached page, or CSS hiding it at a certain width. Check assignment first, then markup, then styling.
Troubleshooting
Blurry images almost always mean WordPress is serving a small generated size scaled up, or compressing the file twice. Match the upload size to the display size and control the compression quality.
