   Please do anything with annoying PHP notices while creating static pages:
   Array to string conversion in \\wp-content\\plugins\\w3-total-cache\\lib\\W3\\Cache.php on line 52
   Page Cache Method: Disk (enhanced).

   it doesn't seem to like this bit of code:

   function &instance($engine, $config = array()) {
   static $instances = array();

   $instance_key = sprintf('%s_%s', $engine, md5(implode('', $config)));

   if (!isset($instances[$instance_key])) {
   switch ($engine) {
   case W3TC_CACHE_MEMCACHED:
   require_once W3TC_LIB_W3_DIR . '/Cache/Memcached.php';
   $instances[$instance_key] = & ne

   Installed latest version today. Getting same error .. Is this a critical error?

   PHP Notice: Array to string conversion in /public_html/wp-content/plugins/w3-total-cache/lib/W3/Cache.php on line 52

   Also I wanted to let you know that sometimes it is still using the ?p=xxx codes and fails to rewrite to the correct URL - I believe it only happens when I am logged in but I need to do further testing.

   Last, but not least I would like to ask where you store the index.html for the index page (blog homepage!) .. I can't find it in w3tc/pgcache/..

   Are you still having this issue with 0.9.2.4?

   Yes, I'm using 0.9.2.4 and am getting this error. Specifically:-

   [26-Jan-2012 11:05:10] PHP Notice: Array to string conversion in /home/sites/wordpress-mu/web/wp-content/plugins/w3-total-cache/lib/W3/Minify.php on line 810
   [26-Jan-2012 11:05:10] PHP Notice: Array to string conversion in /home/sites/wordpress-mu/web/wp-content/plugins/w3-total-cache/lib/W3/Minify.php on line 810
   [26-Jan-2012 14:13:53] PHP Notice: Array to string conversion in /home/sites/wordpress-mu/web/wp-content/plugins/w3-total-cache/lib/W3/Minify.php on line 810
   [26-Jan-2012 14:13:53] PHP Notice: Array to string conversion in /home/sites/wordpress-mu/web/wp-content/plugins/w3-total-cache/lib/W3/Minify.php on line 810

   etc.

   The function called is
   function _generate_id($sources, $type),

   the line is:-
   $id = substr(md5(implode('', $values)), 0, 6);

   I have the JS and CSS minifiers set to manual (so that I can non-block load the Javascript for example).

   Would it be helpful to debug the values for $sources and $type?

   I'm quite comfy debugging and analysing PHP and Linux matters, so if there's something you (Frederick) would like me to try out and report upon I'd be happy to try and report back.

   All the best,
   Hedgehog.
