Inserted PHP Fatal Error in version 6.1

No. My PHP code has no duplicate cleanup function. I changed it to mycleanup and the error just changed to mycleanup.

I don’t know how the jetpack option
Automatically share your posts to social networks.
works but when I turn it off, all works properly. If there had been a duplicate cleanup function, it would not have worked.

One thing I did notice was that “existing” pages that had my own PHP code continued to work (no fatal error). It was only when I built a “new” page with PHP code that failed. Also, if the PHP code doesn’t contain any function at all, there is no error.

[insert_php]
function cleanup() {
  echo "Test<br />";
}
cleanup();
[/insert_php]

The above code on a page relies on the plugin “Insert PHP” by Will Bontrager.

When combined with Jetpack plugin it fails when Jetpack’s
Automatically share your posts to social networks.
is turned on. It works with this feature turned off.

I was trying to distil the problem to its simplest form. I thought the purpose of our discussion was to get to find the cause of the problem not to discover some flaw in my PHP. The question at hand is ‘Why does turning on a feature in Jetpack cause a fatal error related to an attempt to redefine a PHP function?’

The simple PHP “code” I sent you uses the same function name “cleanup” (for the purposes of continuity in our discussion), it is not the “real” code of my “cleanup” function.

My “real” code really does “clean” something. But it has no bearing on the cause of the problem. I’m convinced that if you installed both Jetpack and Insert PHP and created a page with the simplified code I sent, you should find that it fails with the fatal error.

No. Not sure it helps. I’m not familiar with and did not even know I was using “Open Graph Meta Tags”. I assume that you wanted me to add this filter my child theme’s “functions.php”.

It seems simpler for me to just turn off Jetpack’s “Sharing” feature called Automatically share your posts to social networks. I know this is probably using a hammer instead of tweezers but it’s a much more “obvious” approach.

I’ve alerted the author of the Insert PHP plugin as you suggested.

Thanks for confirming the conflict.

I’ve added the filter to my child theme functions.php and can confirm that it has fixed the conflict.

Many thanks for the explanation of Open Graph. Love it or hate it, I realise that Facebook is very powerful in the world of social networks. I don’t want to disadvantage my clients by turning off the Automatic sharing. So I’ve turned it back on.
