 * Hi,
    I am having issues with the latest version of your plugin, where on form
   submission it says either
 * This page isn’t working
    myruby.co.uk didn’t send any data. ERR_EMPTY_RESPONSE
 * Or, occasionally, it will say cannot connect to salesforce.com
 * It used to work fine, before you switched the API to the new salesforce one.
 * Any ideas?
    Many thanks

 * Sounds like issues with your server connecting to Salesforce. Possibly the new
   endpoint due to it’s being configured differently.
 * Unfortunately, that likely has very little (if anything) to do with the plugin…
   and more to do with your server configuration.

 * Hi Nick,
 * Humm, unusual. Please can you confirm the recommended server requirements, ie.
   php ver, allowed IP’s etc? I’m wondering if Wordfence could be blocking it, have
   you experienced this before?
 * Also, is there anything that needs to change on the plugin to enable the new 
   API, or is it enabled by default?
 * Many thanks

 * Nothing special: If you can run WordPress, the plugin _should_ work.
 * It uses the WordPress “remote post” functions to make the remote connection to
   SF, which falls back to curl if needed, has sane defaults, etc.
 * Other users have had issues with timeouts, outdated curl, outdated openssl, etc.
   No common reasons other than their hosting was all configured differently, and
   SF has been removing SSL ciphers and requiring newer versions of TLS (and deprecating
   SSL)… so it’s exposing some poorly managed web hosts.
 * But those are all way below the level of even WordPress and definitely the plugin.
 * As you can imagine, I can’t help you troubleshoot low-level server issues like
   these on this forum.
 * The new endpoint is enabled by default. Switching back is not a valid solution
   as the old endpoint is going away soon.
