 * I was installing the plugin W3 Total Cache on my WordPress site using the default
   theme 2015,and got this error message: Fatal Error: Class ‘W3_PgCache’ not found
   in /usr/home/hitstars11/domains/fanningfamilyhistory.com/public_html/wp-content/
   plugins/wp-cart-for-digital=products/wp_eStore1.php on line 1249
 * I can’t do anything on my Dashboard and just get this fatal error message. I 
   can load my site but that’s all.
 * My site is [Fanning Family History](https://wordpress.org/support/topic/fatal-error-message-135/www.fanningfamilyhistory.com?output_format=md)
 * I don’t know anything about using code so any help needs to be fairly simple.
   
   Thanks in advance.

 * It looks like it is a compatibility issue with this plugin and that plugin. You
   could try using WP Super Cache but chances are is that is just a very old plugin.

 * I was installing the plugin W3 Total Cache on my WordPress multisite using the
   recently updated scroller parallax theme. Now the site has totally crashed and
   isn’t accessible any more.
    Is there anything I could do about it???
