This guide helps you resolve them calmly.<\/p>\n<h2>The 500 Internal Server Error<\/h2>\n<p>A generic server error, usually caused by a plugin or theme conflict, a corrupt .htaccess file, or a low PHP memory limit. To fix it:<\/p>\n<ul>\n<li>Deactivate plugins (rename the plugins folder if you are locked out), then re-enable one by one.<\/li>\n<li>Switch to a default theme to rule out the theme.<\/li>\n<li>Regenerate the .htaccess file by re-saving permalinks.<\/li>\n<li>Increase the PHP memory limit.<\/li>\n<li>Check the error log for the exact cause.<\/li>\n<\/ul>\n<h2>The 403 Forbidden Error<\/h2>\n<p>This means the server is refusing access, often due to file permissions, a security plugin or firewall rule, or a bad .htaccess. To fix it:<\/p>\n<ul>\n<li>Check file and folder permissions (usually 644 for files, 755 for folders).<\/li>\n<li>Review any security plugin that may be blocking access.<\/li>\n<li>Rename .htaccess to test whether it is the cause, then re-save permalinks.<\/li>\n<\/ul>\n<h2>The 404 Not Found Error<\/h2>\n<p>A 404 means the requested page could not be found. If individual posts 404 but the homepage works, it is almost always the permalinks. To fix it:<\/p>\n<ul>\n<li>Ga naar <strong>Settings &gt; Permalinks<\/strong> and click Save to refresh the rules.<\/li>\n<li>Confirm the page or post actually exists and is published.<\/li>\n<li>Set up a redirect if the content moved.<\/li>\n<\/ul>\n<h2>Always check the error log<\/h2>\n<p>Your hosting error log often names the exact file or plugin behind an error, which turns guesswork into a quick fix. Check it whenever an error appears.<\/p>\n<h2>When in doubt, restore a backup<\/h2>\n<p>If an error started right after a change and you cannot pin it down, restoring a recent backup is the fastest route back to a working site.<\/p>\n<h2>Hulp nodig?<\/h2>\n<p>If an error will not budge, our support team can check the logs and help you fix it over live chat.<\/p>","protected":false},"excerpt":{"rendered":"<p>Sooner or later you may hit a WordPress error.
