The white screen of death WordPress problem can affect your entire site or just the admin area.

Common SSL certificate error types include expired certificates, name mismatch errors, and missing intermediate certificates. Learning how to fix SSL errors quickly is critical for maintaining visitor trust and SEO rankings.
Mixed Content Warnings
HTTPS page loading HTTP resources. Browsers block or warn about insecure content.
Site Flagged by Google
Google showing warning that your site may be hacked. Devastating for traffic.
SQL Injection Vulnerability
Security flaw allowing attackers to inject malicious SQL into database queries.
XSS (Cross-Site Scripting) Vulnerability
Attackers can inject malicious JavaScript, stealing user data or hijacking sessions.
Brute Force Login Attacks
Automated attempts to guess passwords. Can lead to account compromise.
WordPress Plugin Conflict
Two or more plugins interfering, causing errors or site crashes.
WordPress Theme Causing Errors
Theme code issues causing site to break or crash.
WordPress Memory Limit Exceeded
PHP running out of allocated memory, causing crashes or failed operations.
Cannot Access WP-Admin
Locked out of WordPress admin panel. Cannot login or page won't load.
WordPress Update Failed
WordPress core, plugin, or theme update failed, potentially leaving site broken.
Corrupted WordPress Database
Database tables corrupted, causing errors or missing content.
Slow Page Load Speed
Website pages load slowly, causing high bounce rates and poor search rankings. Slow website speed affects user experience, conversions, and SEO performance.
Large Unoptimized Images
Oversized images are the most common cause of slow websites. Unoptimized images waste bandwidth, increase load times, and hurt Core Web Vitals scores.
Render-Blocking Resources
JavaScript and CSS files that block the browser from rendering the page, causing delayed First Contentful Paint and poor user experience.
Failing Core Web Vitals
Google's Core Web Vitals (LCP, FID/INP, CLS) failing thresholds, directly impacting search rankings and user experience.
Mobile Responsiveness Issues
Website not displaying correctly on mobile devices. With over 60% of web traffic coming from mobile, responsiveness issues directly impact conversions and SEO.
High Bounce Rate
Visitors leaving your website after viewing only one page. A high bounce rate signals poor user experience, irrelevant content, or slow loading — all of which hurt conversions and SEO.
Low Conversion Rate
Website getting traffic but failing to convert visitors into leads or customers. Low conversion rates mean your marketing spend is being wasted on a site that doesn't close.
Poor SEO Rankings
Website not appearing in Google search results or ranking on page 2+. Poor search visibility means missing out on free, high-intent organic traffic.
Website Not Indexed by Google
Google hasn't indexed your website or specific pages, making them invisible in search results. If Google can't find your pages, they don't exist to searchers.
Email Deliverability Issues
Emails from your website (contact forms, order confirmations, newsletters) landing in spam or not being delivered at all. Poor email deliverability means lost leads and missed customer communications.
