[Solved] WordPress 500 Error After Troubleshooting

My WordPress site shows persistent 500 Internal Server Error. I've completed standard troubleshooting:

- Fixed .htaccess configuration issues
- Adjusted memory limits
- Cleared all caches
- Disabled plugins and themes
- Reinstalled WordPress core via WP Toolkit

Error persists even with all WordPress components disabled. Error logs show "End of script output before headers" errors.

This appears to be a server-level issue. Could you please check:
- Database connectivity
- PHP error logs
- Server resource limits
- File permissions

Thank you for your assistance.

This is definitely not a server level issue since you're the only one reporting the issue, it's likely that your wordpress installation broke while attempting an automatic update.

Try renaming your .htaccess file to something else.

It's because your .htaccess contains php_value statements, which we don't allow (users are not permitted to change PHP settings, especially the memory limit or execution time limits).
 

Invalid command 'php_value', perhaps misspelled or defined by a module not included in the server configuration, referer: https://allpeptides.net/

I just commented it out for you and the 500 error went away. Now it looks like you need to reinstall WP as the software itself is also broken.

Thank you for fixing the .htaccess issue!

It previously returned a 502 error, which is why I tried the php_value, based on suggestions online. I've already attempted to reinstall WordPress core using WP Toolkit's "Check WordPress Integrity" feature and WP-CLI, but the site still has issues.

But will try from scratch this time.

Thank you for your assistance, this issue can be marked as solved now.

No problem.

By the way, a 502 every few hours is actually normal because of Apache restarting to configure new domains and settings. Usually lasts a few minutes and then clears up on its own.
