Hello @mikerinos
I am sorry about the issue you are experiencing and I am happy to assist you with this.
I can see that you are also using Cloudflare so there may be some temporary issues with the Cloudflare integration.
Can you please enable wp_debug and check for any error messages.
Also make sure to completely remove W3 Total Cache with the instructions below and let me know if the problem persists?
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)
Thanks!
Thanks for the fast answer.
I’ve done this and now the site is running with a lot of “Deprecated” errors displayed in the header.
Not sure what to do next…
…turning off debug mode has removed the error messages 🙂
Hello @mikerinos

Thanks for your help!
Hello @mikerinos
Thank you for your feedback.
It seems that these deprecated messages are related to your security plugin so I would advise reaching out to their support for assistance since these are not related to the W3 Total Cache.
Thanks!
