Hello. I am seeing this warning:
Warning: call_user_func_array() expects parameter 1 to be a valid callback, function ‘sp_html_email_admin_options’ not found or invalid function name in /nfs/c04/problem-with-post-edit-button03/mnt/85310/domains/pp-dev3.group218.com/problem-with-post-edit-buttontml/wp-includes/plugin.php on line 496
Can you please explain what that means? Dev website is http://pp-dev3.group218.com.
Thanks.
Ah apologies. I can trace this and we do have a small error there although it should have no actual effect on any processing or option setting. I will open a ticket and get it fixed up.
But… you really should not see notices, warnings and error messages displayed like that. It is considered bad practice and can, of course, when on the front, public side of the website, show path information it is best kept private. If you have not got the debug flag set in the WordPress config file then you should really talk to your host about having these set per php recommendations.
I had previously installed the HTML Emails plugin from Simple:Press. Upon deactivation, this error message went away.
Yes – that is the cause but – as I say – it will have no ill-effect on anything operationally which si the main thing.
