# Rename Media Files on Upload: Advanced Troubleshooting

## Advanced troubleshooting

When Rename Media Files: Improve Your WordPress SEO renames inconsistently after the basic checks, look for a PHP error in the WordPress debug.log and server error logs around the upload time. Then start with a simple filename structure, add tokens and rules one at a time, test with an upload after each change, and back up first.

### Symptom

Renaming behaves inconsistently and the earlier troubleshooting steps did not surface the cause.

### Cause

Deeper issues are usually environment specific: a PHP error during the upload, an overly complex set of rules, or a change made without a fallback to revert to.

### Fix steps

1. **Check your error logs.** Review the WordPress `debug.log` and your server error logs for any entries logged around the time of the upload.
2. **Start simple.** Begin with a basic filename structure, confirm it works, then add tokens and rules one at a time so any conflict is easy to spot.
3. **Test thoroughly.** After each settings change, upload a test file and confirm the result before relying on it for real content.
4. **Back up your site.** Always take a full backup before making significant changes or running bulk operations, so you can roll back if needed.
