500 Internal Server Error

Have you tried:

– deactivating all plugins to see if this resolves the problem? If this works, re-activate the plugins one by one until you find the problematic plugin(s).

– switching to the Twenty Ten theme to rule out any theme-specific problems?

Tried it, the plugin wasn’t it. As for changing themes, if I change to a different theme won’t it screw up the site since the layout is so different? Would it make any difference if I reinstalled WordPress on my site?

It’s something you need to try as part of the troubleshooting process.

Would it make any difference if I reinstalled WordPress on my site?

If you run a re-install, you risk wiping out your database. You can, however, try re-uploading all files & folders – except the wp-content folder – from a fresh download of WordPress.

the solution that helped me was changing a response code from 500 to 200 in wp-includes/functions.php.

XRint,

That’s good that you solved your problem, but please don’t recommend that people modify the core files like that. That’ll make them suffer huge when an update comes around and the real problem comes back right after the update.

If someone does have to replace or overwrite WordPress functions, give this Catswhocode post a read. It’s not 100% on this issue but let’s you modify core functions without actually modifying core functions.

In this case, esmi’s advice is best: troubleshoot the problem and find the actual culprit.

@jan: Totally valid point! Sometimes we just need to make things work now and don’t have time to invest into the perfect solution.
