Can you please manually delete the file, then go to your wp dashboard, and save all settings and purge the cache in the W3TC general settings? Thanks! * Thread Starter [javiernarvaez](https://wordpress.org/support/users/javiernarvaez/) * (@javiernarvaez) * [4 years, 12 months ago](https://wordpress.org/support/topic/problem-293/#post-14512632) * Hi Marko, thank you, the site has not made any configuration changes or new plugins, nothing. Only new posts have been uploaded. The site is now blank so I can’t access the admin to make the changes you ask me to do. If I can access the ftp, and I can delete the file. i do? the site is [http://www.ihistoriapucv.cl](http://www.ihistoriapucv.cl) Thanks * Thread Starter [javiernarvaez](https://wordpress.org/support/users/javiernarvaez/) * (@javiernarvaez) * [4 years, 12 months ago](https://wordpress.org/support/topic/problem-293/#post-14512637) * In order to see the warning problem that I showed in the previous post, I had to do a “debug false” in wordpress. If I don’t, everything is blank. * Plugin Contributor [Marko Vasiljevic](https://wordpress.org/support/users/vmarko/) * (@vmarko) * [4 years, 12 months ago](https://wordpress.org/support/topic/problem-293/#post-14512923) * Hello @, * Please follow the steps below to completely remove W3 Total Cache: 1. Check . htaccess File (make backup) W3TC will create many directives in .htaccess file to control the caching behavior. Each section will start and end with comments like “#BEGIN W3TC Page Cache core” and “#END W3TC Page Cache core”. Ensure that no residual entries are left over in your .htaccess file after deleting the plugin. 2. Delete wp-content files and folders – cache folder – w3tc-config folder – object-cache.php (if exists) – advanced-cache.php (if exists) – db.php (if exists)– upgrade folder – delete w3-total-cache folder in wp-content/plugins/ (if exists) 3. Delete Cached Files from CDN (if using CDN) Besides deleting all the relevant files, if you use CDN then ensure to purge the cached content from your CDN. This is necessary when you enabled minify option in W3TC settings. You should delete the minified and combined scripts and CSS files from your CDN server to avoid the site breaking on the browser. 4. Go to your wp dashboard and re-install W3 Total Cache Thanks! * Thread Starter [javiernarvaez](https://wordpress.org/support/users/javiernarvaez/) * (@javiernarvaez) * [4 years, 12 months ago](https://wordpress.org/support/topic/problem-293/#post-14513300) * I feel a little desesperated you tell me erase files. The site depends of this files? o if i erase i can recover the site….thats good? the site can be recover? please helpme. * Hi, im trying to delete all the files you tellme: * – all the content of .htaccess file is on this lines: “#BEGIN W3TC Page Cache core” and “#END W3TC Page Cache core” I make a backup and deleted all the content of.htaccess * – cache folder i cant delete, i cant have permissions to delete. – w3tc-config folder – Deleted – object-cache.php no exists on the folder – advanced-cache. php – Deleted – db.php no exists on the folder – upgrade folder – deleted (it was empty) – w3-total-cache on plugins folder, deleted. * 3. Delete Cached Files from CDN (if using CDN) Where i can see this files? is plugin? I think i dont have this service. * The site continues on blank… What else can I do? * Plugin Contributor [Marko Vasiljevic](https://wordpress.org/support/users/vmarko/) * (@vmarko) * [4 years, 11 months ago](https://wordpress.org/support/topic/problem-293/#post-14515072) * Hello [@javiernarvaez](https://wordpress.org/support/users/javiernarvaez/) * These are W3TC files so you should not worry about using the content. As for the cache folder please reach out to your hosting provider for permission to delete it. If you are not using the CDN you should not worry about step 3. You should not delete the entire .htaccess file. You should only delete the W3TC lines within the .htaccess file and keep all other lines. I hope this helps!
