 * I don’t see anything in documentation regard requirements of PHP version.
    Is
   an Upgrade of PHP to verion 7.1.8 required to work with recent update? We had
   sites imploding after the most recent update until we migrated sites to servers
   with upgraded from PHP Version 5.3.3 to PHP Version 7.1.8 All sites are running
   WordPress Version 4.8.1 and the migrated sites work. It would be nice if an update
   would warn of this requirement instead of toasting the site. Great plugin though!!

 * Could you *please* let us know what the PHP requirements are for CF7????
 * Will it work with PHP 5.2?
 * Will it work with PHP 5.3?
 * Will it work with PHP 5.4?
 * Will it work with PHP 5.6?
 * You get the idea…

 * Sorry about my delayed response.
    By imploding I mean becoming totally unusable
   when updating the plugin. The one plugin in common on sites not functioning was
   contact form 7. When the plugin was disabled the sites worked again. When we 
   moved from a server running PHP Version 5.3.3 to a server running PHP Version
   7.1.8 we were able to run the updater and no crashes. It made me wonder if there
   was a version of PHP required or recommended, what versions have been tested 
   or are no longer supported.

 * Just had 2 sites throw errors after upgrading to php7. Both instances, the person
   monitoring the site said it was a Contact Form 7 issue. Won’t be able to look
   at it until tonight.
