What this page covers
A practical way to find what’s spamming your WordPress logs, save a copy, and clean the log safely—using a lightweight plugin that can both view and clear debug.log.
Where most “log cleanup” attempts go wrong
People delete the file blindly, lose the evidence, and then can’t reproduce the error. The better workflow is: backup → reproduce → review → then clear (so the next errors are easy to spot).
How to clean WordPress logs without losing the evidence
If you searched for a “WordPress plugin for cleaning logs”, you’re probably dealing with a debug.log that keeps growing, eating disk space, or making troubleshooting painful.
“Cleaning logs” is usually simple: review what’s inside, save a copy, then clear the log so new errors become obvious.
What “debug.log” is (and where it lives)
When WordPress debugging is enabled with WP_DEBUG_LOG, errors are written to wp-content/debug.log. That file is your evidence trail—don’t throw it away before you’ve looked at it.
A safe workflow: backup → reproduce → review → clear
1) Download a copy first (always)
Before you wipe anything, save the current log. If you end up contacting a developer or plugin support, that file is often the fastest way to get help.
2) Reproduce the issue (so the next log is “clean”)
After you’ve saved the log, try to reproduce the problem that’s spamming errors (checkout, a form submit, a cron task, a specific admin page). This makes the next log entries meaningful.
3) Search and filter before you delete
A long debug.log is usually repetitive. Find the repeating pattern first: same plugin file path, same warning line, same request route. That’s how you pinpoint the real culprit quickly.
4) Clear the log to reset the signal
Once you’ve saved a copy and you understand what’s repeating, clear the log. A fresh debug.log makes new errors stand out immediately.
Using Quick Debug Log Viewer for log cleanup
Quick Debug Log Viewer is built specifically for this workflow: it lets you open the debug log, search and filter entries, download the log, and clear it when you’re ready.
Why it’s useful specifically for “cleaning logs”
- Download log before you wipe it (keeps your evidence).
- Clear log to stop a bloated file from growing.
- Search + filters to spot repeating errors fast.
- Load more to handle large logs without pain.
Tip: keep a “before” and “after” log
Support conversations go faster when you can share: (1) the bloated log, (2) a clean log created right after reproducing the issue. It turns guessing into evidence.
What cleaning logs does NOT do
Clearing debug.log doesn’t fix the underlying error. It just resets the noise. The real win is that you can immediately see what comes back after you reproduce the issue—then fix that root cause.
Next step
If you want the fastest path: open the plugin, download your current debug.log, reproduce the issue, then clear the log and watch what reappears. That’s the cleanest troubleshooting loop you can run on a busy WordPress site.
- A safe cleanup workflow you can repeat anytime
- A clean “before/after” log you can share with support
- A simple way to search and filter errors before wiping
- One-click download, then clear the log when you’re ready
