Thanks for pointing me in the right direction with the module John. You've made it so simple.

I am sorry to report on the warnings issue though, that the Hosting Provider spent some time on this troubleshooting, and believe that the plugin may need updating. They did add a php.ini but it did not solve the issue. They wondered if the plugin may have been out of date. I mentioned I had been using this plugin since before its Sep 2016 update, and the warnings had started since before that update. They occur only when FB share counter is set to show. No issue if FB share counter is set to hide. Sep 16 plugin update did not resolve the issue. The Host suggested that there is a script error in the php code that may need debugging. We also tried changing to BEEZ template but warnings persisted.

It is a beautiful piece of code. Hope we can get the conflict debugged. Many thanks again. Kind regards
