Update Error

In your Wordfence Options, turning on “Disable config caching” — if the file still exists after that (wp-content/plugins/wordfence/tmp/configCache.php), you can remove it. If that was the only file blocking the update, it should work after that. If not, let us know.

I am getting the same error message and have turned on “Disable config caching” I still can’t get it to update. I have no clue on how to remove the file.

Please advise. Thank you

I had the same error.

I turned off config caching and I still got the error.

I ssh’d in to the machine and manually deleted the file /<wordpress root>/wp-content/plugins/wordfence/tmp/configCache.php and then re-ran plugin update. Then it worked.

Yup, same here. I disabled the option and used my file manager to delete that one file. Update went through without a hitch after that.

Deleting the configCache.php file worked for me. Thanks!

Thanks everyone for confirming the fix has worked for you.

mudstompers: You can use FTP or your host’s file manager to remove the file. If you haven’t done that before, you can go to your WordPress plugin list, deactivate Wordfence, remove it from the site, then install it again. Your settings should still be there, as long as you have not turned on the option to delete them.

I got the new version by deleting wf, then reinstalling it. However I still cannot run a scan. Please advise.

When you try to run a scan, what happens? Does anything happen when you click the button at all?

There are some troubleshooting steps for scans that won’t start, that you can follow, here:
My scans aren’t starting

If this doesn’t help, if clicking the Scan button starts to show information in the yellow boxes on the scan page, but then it gets stuck, can you post the results from both boxes here? (If it’s long, you can use pastebin.com or a similar service — please don’t paste more than about 10 lines here.)

Deleting the configCache.php file worked for me. Thanks!
As a novice user of WordPress, deleting a file that deep felt like doing neurosurgery on my own brain. Nothing to it. Just drill a hole with the file manager, move the wordpress, plugins, and cerebellum out of the way and take out the file.
If anything goes wrong, you won’t know it as your brain will shut down.
Then you can work at the post office without getting frustrated!

Deleting the configCache.php file, /wp-content/plugins/wordfence/tmp/configCache.php file
AND
Disabling the WordFence>Diagnostics>Disable config caching worked.

The Disable config caching option is on the Diagnostics menu, the bottom of the page in WordPress.
Click the Wordfence plugin settings menu option on the left-hand side of the screen, then click the Diagnostics menu item.
Scroll to the bottom of the page and select the Disable config caching, save your changes and install.

You may want to re-enable the option after a successful installation.
