Minor website update, code fix.

Lug 26, 2019 by Dr. Leslie Dean Brown

You may or may not have noticed this but there was an error code appearing on the top of all our main pages for some time (two years) which said:

“Warning: call_user_func_array() expects parameter 1 to be a valid callback, function ‘greenday_head’ not found or invalid function name in /home/xnvrtebr/public_html/Blog/wp-includes/class-wp-hook.php on line 286”.

We’ve been using the same theme on our website since mid-2008. Over ten years! My how time flies!

We didn’t even notice the error straight away because it was black text appearing on a black background. That meant it was harder to track what went wrong and where.

Over time we’ve made numerous incremental changes to our website to make it more professional, more streamlined, more straightforward, more interesting to read, easier to navigate, and above all – faster loading. Unfortunately that meant it was harder to track what went wrong and where. I had essentially given up on trying to solve it myself and was totally prepared to hand the issue over to a freelance coder or something that could get the job done a lot faster.

I even tried to contact the original wordpress theme author but that didn’t work. Anyway, today, I’m pleased to report that that issue has now been resolved. Finally!
