Kept getting this error: "W3 Total Cache Error: some files appear to be missing or out of place. Please re-install plugin or remove /home/rlancet/public_html/wp-content/advanced-cache.php.
Had to do the Filezilla and delete three files from the W3 Advanced Cache."
I deleted in wp-content file the advanced-cache.php,db.php, and other.php
and finally can login to my wordpress dashboard.
Tada! Now back into login and creating content....frustration for a few days and now feel lighter that I fixed the problem.
