Further errors appear when we try to make updates to the site (after clicking ‘Update’ on a post/page entry):
Warning: Incorrect cache engine in /…/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 /…/public_html/wp-content/plugins/w3-total-cache/lib/W3/Cache.php:76) in /…/public_html/wp-includes/pluggable.php on line 876
Edits do appear to go through, but something is clearly wrong here…
The plugin uses the same method as WordPress to retrieve the plugin idea. It checks global $posts make sure there is no issue with other plugins. global posts should not contain WP_Query. From the Codex http://codex.wordpress.org/The_Loop:
“The $wp_query takes the arguments and builds and executes a DB query that results in an array of posts. This array is stored in the object and also returned back to the blog header where it is stuffed into the global $posts array (for backward compatibility with old post loops).”

Thanks for the info, but I’m not exactly sure how that helps me…
To give you a fuller picture of the situation, users logged into WP do not see the toolbar and receive an error message on pages only while the W3 Total Cache plugin is enabled since I updated. As soon as the plugin is disabled, the toolbar appears correctly across the site. Posts do not have the same problem (that is to say, the toolbar appears when viewing the blog section of our site).
What actions do you recommend?
