Title: Cannot update Wordfence Last modified: August 30, 2016 --- # Cannot update Wordfence * Resolved [beatriz herrera](https://wordpress.org/support/users/beatriz-herrera/) * (@beatriz-herrera) * [10 years, 8 months ago](https://wordpress.org/support/topic/cannot-update-wordfence/) * Hi, I’m still having trouble updating to version 6.0.16 of wordfence. * I’ve never had problems updating a plugin before. * I got the following message: “The update cannot be installed because we will be unable to copy some files. This is usually due to inconsistent file permissions. tmp/configCache.php” * I tried changing the configCache.php from 644 to 755. Nothing. * Then it was suggested (i’d erroneously posted a question on a resolved topic) that I change my caching options to not cache config, then simply delete the configCache.php file. * I don’t have caching set up through Wordfence. I’m using W3 total cache and I don’t have any options about caching config files? * I’ve also gone through all my wp files, from admin to each plugin. I don’t see any file permissions that have changed at all. I have everything set up either as 644 or 755. * I also tried activating and deactivating the plugin. * I’m sure it is something very simple that I’m failing to see? I hope! I’m still very new at this. * Thank you, * Beatriz Herrera [](http://beatrizherrera.ca) * [https://wordpress.org/plugins/wordfence/](https://wordpress.org/plugins/wordfence/) Viewing 11 replies - 1 through 11 (of 11 total) * [WFBrian](https://wordpress.org/support/users/wfbrian/) * (@wfbrian) * [10 years, 8 months ago](https://wordpress.org/support/topic/cannot-update-wordfence/#post-6545999) * Hi Beatriz, * You said that you you’ve tried activating/deactivating the plugin. Did you check the option to Remove Table Data? You might want to export your settings if you’ve made a lot of customizations before doing this. Removing Wordfence and table data will give you a clean slate to try installing 6.0.16 from scratch (i.e. not an update install). * configCache.php does not have to do with Falcon Caching. It stores Wordfence configuration variables to speed up performance. * Thanks, Brian * Thread Starter [beatriz herrera](https://wordpress.org/support/users/beatriz-herrera/) * (@beatriz-herrera) * [10 years, 8 months ago](https://wordpress.org/support/topic/cannot-update-wordfence/#post-6546027) * Hi! * Thank you for the advice. It updated finally. * In the end I tried (again) -exporting my settings as you suggested. then under Options/Other options: checked Disable config caching, saved, emptied caches, reloaded, then went into my server files, found and deleted configCache.php file in wp-content/plugins/wordfence/tmp/configCache.php * I’ll keep my eye on it over the next little bit, and if something happens again I’ll clear the table data and reload from scratch. * But I think it’s ok! thank you! * beatriz * [jjazzbel](https://wordpress.org/support/users/jjazzbel/) * (@jjazzbel) * [10 years, 5 months ago](https://wordpress.org/support/topic/cannot-update-wordfence/#post-6546364) * Deleting configCache.php file in wp-content/plugins/wordfence/tmp/configCache. php worked for me. * Thank you. * Plugin Author [WFMattR](https://wordpress.org/support/users/wfmattr/) * (@wfmattr) * [10 years, 5 months ago](https://wordpress.org/support/topic/cannot-update-wordfence/#post-6546365) * [@jjazzbel](https://wordpress.org/support/users/jjazzbel/): Thanks for confirming that it helped — this is relatively rare, but our dev team is aware and working on preventing this in future versions. * -Matt R * [Han Balk](https://wordpress.org/support/users/beam63/) * (@beam63) * [10 years, 5 months ago](https://wordpress.org/support/topic/cannot-update-wordfence/#post-6546366) * Had the same issue. * Deleting configCache.php file in wp-content/plugins/wordfence/tmp/configCache. php worked for me too. * Thanks for the info. * [devrap](https://wordpress.org/support/users/devrap/) * (@devrap) * [10 years, 3 months ago](https://wordpress.org/support/topic/cannot-update-wordfence/#post-6546370) * Still happening as recent as your second-to-latest version. I was just able to update today by deleting configCache.php file from wp-content/plugins/wordfence/ tmp/configCache.php –so grateful for having found this post, because I fell into a k-hole of other WP update issues that were unrelated. * [lincswebdesign](https://wordpress.org/support/users/lincswebdesign/) * (@lincswebdesign) * [10 years ago](https://wordpress.org/support/topic/cannot-update-wordfence/#post-6546380) * Work for me on the latest version many thanks I just deleted the wp-content/plugins/ wordfence/tmp/configCache.php worpress version 4.5 * [Irina Blumenfeld](https://wordpress.org/support/users/iblum/) * (@iblum) * [10 years ago](https://wordpress.org/support/topic/cannot-update-wordfence/#post-6546381) * I’m glad I found this post. Deleting wp-content/plugins/wordfence/tmp/configCache. php fixed it for me too.

Usually I just delete the plugin and reinstall the latest, I found this post and deleted the configCache.php and emptied all caches, but its still failing the update * [Nancy J.
