 * We are seeing this 500 error on our site:
 * [Wed Apr 24 12:29:51.279818 2019] [php7:notice] [pid 26422] [client 134.106.87.67:
   20738] WordPress database error Got a packet bigger than ‘max_allowed_packet’
   bytes for query UPDATE `wp_options` SET `option_value` = ‘a:511689:
 * The max_allowed_packets can not exceed 16M and the total value appears to be 
   exceeding that amount. Looking over the data it seems like it’s related to this
   
   pardot plugin, which seems to be trying to update an option value with a large
   serialized array for all pardot accounts.
 * Is there a way around this?

 * Hey [@rmwebsite](https://wordpress.org/support/users/rmwebsite/),
 * This is a known bug with the current version of the plugin. Take a look at the
   recommendations here: [https://wordpress.org/support/topic/site-times-out-from-transient_keys-and-cache_keys/#post-11177934](https://wordpress.org/support/topic/site-times-out-from-transient_keys-and-cache_keys/#post-11177934)
 * If you would, let me know if that fixes it for you like it has others. I’m preparing
   this fix for a future release.
