Hi,
Thanks for the info I have followed your suggestions, and unfortunately we have not resolved the problem here is what we found:
Renamed the plugin folder just get a blank white screen when trying to access website and access admin dashboard.
When going to the wp-admin login page got the following error: W3 Total Cache Error: some files appear to be missing or out of place. Please re-install plugin or remove /home/fiddesracing/public_html/wp-content/advanced-cache.php.
Renamed the file above and W3 Total Cache still cannot access the dashboard.
As soon as I reverted back the plugins folder to its original name website loaded as before and just quode option on the admin dashboard.
Then tried renaming the theme folder I get a white blank screen when trying to load the website and the following error when trying to load wp-admin
