迁移至GoDaddy Flesk服务器后WordPress增改内容报500错误求助

Hey there, let's tackle this 500 error you're facing after moving your WordPress site to GoDaddy's Flesk server when editing or creating posts/pages. I've dealt with similar issues before, so here are the most likely fixes to try out:

GoDaddy servers can be pretty strict about permissions, and incorrect settings are a common trigger for 500 errors. Make sure your WordPress files and folders have the right access levels:

• All folders should be set to 755
• All files (including wp-config.php) should be set to 644

You can adjust these via cPanel's File Manager, or use SSH commands if you have access:

find /path/to/your/wordpress -type d -exec chmod 755 {} \;
find /path/to/your/wordpress -type f -exec chmod 644 {} \;

Just replace /path/to/your/wordpress with the actual directory path of your site.

The generic 500 error doesn't tell us much—let's dig into the actual problem by turning on WordPress debug:

• Open your wp-config.php file
• Look for the line define('WP_DEBUG', false); and replace it with:

define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);

This will log errors to wp-content/debug.log instead of showing them publicly. Try editing a post again, then check that log file—it'll give you a specific error message pointing to the root cause (like a faulty plugin, theme conflict, or memory limit issue).

Often, 500 errors when editing posts happen because WordPress doesn't have enough memory to process the action. Let's bump that up:

• In wp-config.php, add this line right before /* That's all, stop editing! Happy publishing. */:

define('WP_MEMORY_LIMIT', '256M');

• You can also adjust the PHP memory limit via GoDaddy's cPanel: Go to Select PHP Version > Options, find memory_limit, and set it to 256M or higher.

A misbehaving plugin or theme is one of the top culprits here. Let's test this:

• Rename the plugins folder in wp-content to plugins_old—this disables all plugins at once. Try editing a post again. If it works, rename the folder back to plugins and re-enable them one by one until you find the faulty one.
• If plugins aren't the issue, switch to a default theme like Twenty Twenty-Four. Rename your current theme's folder in wp-content/themes to something else, which will force WordPress to use a default theme. If editing works now, your original theme is the problem.

GoDaddy has some unique configurations that might be causing this:

• Ensure your site is using a supported PHP version (WordPress recommends PHP 7.4 or higher—verify this in cPanel's Select PHP Version).
• Check if mod_security is blocking the edit action. Sometimes GoDaddy's mod_security rules flag post edits as suspicious. You can disable it temporarily via cPanel's ModSecurity tool, or contact GoDaddy support to adjust the rules.
• Try switching PHP handlers: In cPanel's Select PHP Version > Handler, toggle between suPHP and CGI—this can fix permission-related 500 errors.

Corrupted core files can cause odd 500 errors. Download a fresh copy of WordPress, extract it, and upload all files except the wp-content folder and wp-config.php to your server. This replaces any damaged core files without touching your themes, plugins, or settings.

After trying these steps, you should be able to narrow down the issue and get post editing working again. If you find a specific error in the debug log, feel free to share it and we can dive deeper!
