  • I’m getting it too, no idea how to fix it at this point.

    I’ve also been getting it for the last day since upgrading the plugin…

    I’m having the same problem. It happens when I try to edit and save an existing post. I tested with comments, but I use Disqus so it doesn’t seem to affect the comments. Here’s the full error:

    Warning: Incorrect cache engine in HOME_DIR/wp-content/plugins/w3-total-cache/lib/W3/Cache.php on line 76

    Warning: Cannot modify header information – headers already sent by (output started at HOME_DIR/wp-content/plugins/w3-total-cache/lib/W3/Cache.php:76) in HOME_DIR/wp-includes/pluggable.php on line 876

    Also having the same issue. Have been on plugin page but can’t see any info on it.

    Warning: Incorrect cache engine in /home/proprodu/public_html/wp-content/plugins/w3-total-cache/lib/W3/Cache.php on line 76.

    Warning: Cannot modify header information – headers already sent by (output started at /home/proprodu/public_html/wp-content/plugins/better-wp-security/inc/secure.php:1089) in /home/proprodu/public_html/wp-includes/pluggable.php on line 876

    Hope a fix comes through fast as it’s causing a few issues for me including contact page text formatting. Also can’t upload new header design.

    Have you tried resaving the settings from the General Settings page? Also make sure that there are engines listed and selected for Page Cache, Database cache and Object Cache if you have them enabled. The error means that a cache engine that does not exist is being used. Possible cause is a corrupt configuration/settings file so the plugin can’t figure out which engine is being used.

    @frederick: Thanks for the terrific support again. I had this issue. Saving General Settings returned an error regarding rights. After chmod I was able to save settings and the issue is gone now.

    Thanks, that did the trick!!!!

    I tried all of the above and continue to get those errors.

    Performance > General Settings – Click ‘Save all settings’ button

    Then click ‘Enable’ button

    Then click ‘Deploy’ button

    Blessings..

    When I try to log into my wordpress admin, I receive this error message:

    Warning: Incorrect cache engine in /home/erin/public_html/websiteaddress.com/wp-content/plugins/w3-total-cache/lib/W3/Cache.php on line 76

    Warning: Cannot modify header information – headers already sent by (output started at /home/erin/public_html/websiteaddress.com/wp-content/plugins/w3-total-cache/lib/W3/Cache.php:76) in/home/erin/public_html/websiteaddress.com/wp-includes/pluggable.php on line 876

    I logged into cpanel but I am not sure how to fix this one. Do I delete the w3-total-cache.php from my plug ins folder?

    Any advice would be greatly appreciated.
