 * I love the plug-in and it works great expect for some problems I’ve been having
   with DBFlush attempts. When I try to update a post I get the following error 
   message:
 * > Fatal error: Call to undefined method wpdb_wptunerversion::flush_cache() in[
   > absolute path redacted]/wp-content/plugins/w3-total-cache/lib/W3/Plugin/DbCache.
   > php on line 219
 * I can get around this error by disabling DB Caching in the options, that works,
   but it also generates an error:
 * > Fatal error: Call to undefined method wpdb_wptunerversion::flush_cache() in[
   > absolute path redacted]/wp-content/plugins/w3-total-cache/lib/W3/Plugin/TotalCache.
   > php on line 2424
 * That same error also appears when I re-enable DB caching and if I try to manually
   delete the DB cache or use the “empty all cache” option on the main settings 
   page.
 * Any suggestions?

 * You’re using WPTuner ([http://wordpress.org/extend/plugins/wptuner/](http://wordpress.org/extend/plugins/wptuner/))
   right? I do not think it’s compatible. Please disable it and let me know if the
   problem goes away. BTW, I recommend: [http://wordpress.org/extend/plugins/wp-dbmanager/](http://wordpress.org/extend/plugins/wp-dbmanager/)
   instead.
