What is a White Screen?
A white screen is a common issue where your website, app, or browser shows a completely blank white page instead of loading content. It can happen on WordPress sites, mobile apps, or even browsers.
Main Causes of White Screen
1. Plugin or Theme Error
In WordPress or similar platforms, a broken plugin or theme can cause the screen to go white.
2. Memory Limit Issue
If your site uses more memory than allowed, it may stop loading and show a blank screen.
3. Coding Error
A small mistake in PHP, HTML, or JavaScript code can break the page.
4. Browser Problem
Sometimes cache or cookies in your browser cause loading issues.
5. Server Issue
A slow or misconfigured server can also result in a white screen.
How to Fix White Screen Problem
1. Disable Plugins
Turn off all plugins and check if the site starts working again. Then enable them one by one.
2. Switch Theme
Change your current theme to a default one to check if the issue is theme-related.
3. Increase Memory Limit
You can increase PHP memory limit from hosting settings or wp-config file.
4. Clear Browser Cache
Clear cookies and cache or try opening the site in incognito mode.
5. Check Error Logs
Server error logs can help you find the exact issue.
