 * on my site I got a bunch of errors regarding deprecated after the host’s
    server
   had an upgrqade this week to phph 5.3.9
 * W3 Total Cache was the only plugin falling over. I edited some of the files (
   identified as Minify.php and tempcache.php in plugins/w3-total-cache/lib/W3/Plugin/)
   to elimate the errors by removing the & in lines with `=& new` (which has been
   deprecated in php 5) to read `= new` this removed a chunk of the error lines 
   but the rest of the deprication errors couldn’t be resolved that way.
 * I have had to deactivate the plugin for now. I will reactivate at the next update.
   Still a great plugin!
 * The remaining lines are:
 *     ```

 * Well deprecated is not a big deal. Plugin still functions. Could lower your error
   notification and add & ~E_DEPRECATED to error_reporting .

 * As I don’t have access to my php.ini file I added
    `ini_set('display_errors',
   0);` to my wp-config.php file right after the first <?php
 *     ```
       <?php
   
       ini_set('display_errors',0);
       ```
   
 * That stop the errors showing on the public sideAND on my WP dashboard There are
   however deprecation errors on the the incoming links panel.
 * That, said… when I clear the W3TC’s cache it spews out more deprecation errors
   and breaks the page – indicated deprecation errors are in W3’s PgCacheFlush.php&
   Cache.php files.
 * Can I exclude the E_Deprecation on in `i_set('display_errors',0);` instead of
   the 0 or do I need the `error_reporting` line as well?

   for now.
