Plugin Conflicts or Bugs<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Plugins are the #1 cause of WordPress critical errors.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u3053\u308c\u306f\u6b21\u306e\u3088\u3046\u306a\u5834\u5408\u306b\u3088\u304f\u767a\u751f\u3057\u307e\u3059:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A plugin update introduces incompatible code<\/li>\n\n\n\n<li>2\u3064\u306e\u30d7\u30e9\u30b0\u30a4\u30f3\u304c\u7af6\u5408\u3057\u3066\u3044\u307e\u3059<\/li>\n\n\n\n<li>A plugin is not compatible with your PHP version<\/li>\n\n\n\n<li>A plugin uses deprecated WordPress functions<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Page builders, performance plugins, security plugins, and e-commerce extensions are especially common triggers.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Theme Issues and Theme Updates<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Themes can also cause fatal errors, especially when:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A theme update removes or changes required functions<\/li>\n\n\n\n<li>Custom code is added incorrectly to <code>\u95a2\u6570.php<\/code><\/li>\n\n\n\n<li>A child theme is missing dependencies<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">If your site crashes right after changing or updating a theme, this is a strong signal.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. PHP\u30d0\u30fc\u30b8\u30e7\u30f3\u306e\u975e\u4e92\u63db\u6027<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Your hosting server runs a specific PHP version.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>PHP is updated automatically by the host<\/li>\n\n\n\n<li>Your plugins or theme don\u2019t support the new version<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">WordPress may fail instantly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Many older plugins still rely on outdated PHP syntax, which modern PHP versions reject.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. \u30e1\u30e2\u30ea\u5236\u9650\u306e\u67af\u6e07<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">WordPress requires memory to run scripts.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A critical error may occur if:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Too many plugins load at once<\/li>\n\n\n\n<li>A heavy page builder runs complex layouts<\/li>\n\n\n\n<li>WooCommerce processes large queries<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">When PHP memory is exhausted, execution stops.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">5. Corrupted Core Files or Incomplete Updates<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Interrupted updates can leave WordPress in an unstable state.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This can happen due to:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Server timeouts<\/li>\n\n\n\n<li>Connection drops<\/li>\n\n\n\n<li>Insufficient file permissions<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">As a result, essential core files may be missing or corrupted.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">6. Incorrect Custom Code<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Adding code manually\u2014whether in a theme file, custom plugin, or snippet manager\u2014can easily cause fatal errors if syntax is incorrect.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Even a missing semicolon can break the entire site.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How WordPress Helps You Recover from Critical Errors<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Modern WordPress includes a recovery mode.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When a critical error occurs:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>WordPress sends an email to the site admin<\/li>\n\n\n\n<li>The email includes a secure recovery link<\/li>\n\n\n\n<li>This link allows you to log in and disable the problematic plugin or theme<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This feature has made troubleshooting significantly easier compared to older versions.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">\u30b9\u30c6\u30c3\u30d7\u30d0\u30a4\u30b9\u30c6\u30c3\u30d7\uff1aWordPress\u306e\u91cd\u5927\u306a\u30a8\u30e9\u30fc\u3092\u4fee\u6b63\u3059\u308b\u65b9\u6cd5<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Here\u2019s a safe, structured approach.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">\u30b9\u30c6\u30c3\u30d71: \u56de\u5fa9\u30e1\u30fc\u30eb\u3092\u78ba\u8a8d\u3059\u308b<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Always start by checking your admin email inbox.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If WordPress detected the issue, it will tell you:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Which plugin or theme caused the error<\/li>\n\n\n\n<li>How to access recovery mode<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This is often the fastest fix.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 2: Disable All Plugins (If Needed)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If you can\u2019t access wp-admin:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Log in to your hosting file manager or FTP<\/li>\n\n\n\n<li>Navigate to

class=\"wp-block-paragraph\">If the site loads, the issue is plugin-related.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 3: Reactivate Plugins One by One<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">\u30d5\u30a9\u30eb\u30c0\u540d\u3092\u5143\u306b\u623b\u3057\u307e\u3059 <code>\u30d7\u30e9\u30b0\u30a4\u30f3<\/code>, then:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Activate plugins individually<\/li>\n\n\n\n<li>Refresh the site after each activation<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">When the error returns, you\u2019ve found the culprit.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">\u30b9\u30c6\u30c3\u30d74: \u30c7\u30d5\u30a9\u30eb\u30c8\u306e\u30c6\u30fc\u30de\u306b\u5207\u308a\u66ff\u3048\u308b<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If plugins aren\u2019t the issue:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>\u30a2\u30af\u30c6\u30a3\u30d6\u306a\u30c6\u30fc\u30de\u30d5\u30a9\u30eb\u30c0\u306e\u540d\u524d\u3092\u5909\u66f4\u3059\u308b<\/li>\n\n\n\n<li>WordPress\u306f\u81ea\u52d5\u7684\u306b\u30c7\u30d5\u30a9\u30eb\u30c8\u306e\u30c6\u30fc\u30de\u306b\u623b\u308a\u307e\u3059<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">If the site works again, the theme is responsible.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 5: Check PHP Version Compatibility<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Inside your hosting panel:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Try switching to a different PHP version<\/li>\n\n\n\n<li>Test commonly supported versions like PHP 8.0 or 7.4<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Many WordPress environments stabilize immediately after this change.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 6: Increase PHP Memory Limit<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Low memory is a silent killer.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u7de8\u96c6\u3059\u308b\u3053\u3068\u3067\u30e1\u30e2\u30ea\u3092\u5897\u3084\u3059\u3053\u3068\u304c\u3067\u304d\u307e\u3059 <code>wp-config.php<\/code>:<\/p>\n\n\n\n<p

page builders.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 7: Enable Debug Mode for Deeper Insight<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">For persistent issues, enable debugging:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">define(&#8216;WP_DEBUG&#8217;, true);<br>define(&#8216;WP_DEBUG_LOG&#8217;, true);<br>define(&#8216;WP_DEBUG_DISPLAY&#8217;, false);<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Then review the error logs to identify exact causes.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to Prevent WordPress Critical Errors Long-Term<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Fixing the issue is one thing. Preventing it is what really matters.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. Use Quality Plugins Only<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">\u907f\u3051\u308b\uff1a<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>\u653e\u68c4\u3055\u308c\u305f\u30d7\u30e9\u30b0\u30a4\u30f3<\/li>\n\n\n\n<li>Poorly reviewed tools<\/li>\n\n\n\n<li>Plugins updated years ago<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Stick to actively maintained, well-supported plugins.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Always Test Updates<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Never update directly on a live business website.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u4f7f\u7528\uff1a<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Staging environments<\/li>\n\n\n\n<li>Backup snapshots<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This is especially important for cross-border e-commerce sites.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3.
