I think this has to do with php output buffering. Whether it is on or not in your php.ini I have been changing back and forth to see the difference if any. Altho this I do not use this plugin anymore or google fonts for that matter but maybe this could help you track it down.
Hi,
I had this message at one point too.
You can delete or comment out 4 lines of code in the plugin to get rid of it. Though, I don’t seem to have the issue anymore and having the flush on enables my sight to load a little faster with the flush working correctly.
The code starts on line 382…
// The observer flush
function googlefonts_ob_end_flush() {
if (self::gwfo_can_ob())
ob_end_flush();
}
You can change it to this…
// The observer flush
/*
function googlefonts_ob_end_flush() {
if (self::gwfo_can_ob())
ob_end_flush();
}
*/
Or simply delete it.
This is in file
google-webfont-optimizer.php
to be clear..
Hello Noahj,
I did that and now I get this message…
Warning: call_user_func_array() expects parameter 1 to be a valid callback, class 'GWFO' does not have a method 'googlefonts_ob_end_flush' in /home/domain/public_html/wp-includes/plugin.php on line 525
Any ideas?
thanks,
Netivity
