get_currentuserinfo() is deprecated since version 4.5

i have written a small instruction copy about how to find out which of your plugins are generating this error message and how to fix it:
https://www.mashshare.net/fix-the-error-get_currentuserinfo-is-deprecated-in-wordpress/

Not only mailpoet is using the deprecated function get_currentuserinfo ().
As the warning message does not give us a clue where get_currentuserinfo() is used i was thinking the instruction could be useful for the one or other.

Hi mitishi Hi Rene Hermenau
Thanks a lot for the advices. Now my Websites have no errors.
Best regards

A quick way to narrow down where this is coming from is to open up wp-includes\functions.php and temporarily add a stack dump above where this error is generated. To display a stack dump, you can use:

debug_print_backtrace(DEBUG_BACKTRACE_IGNORE_ARGS);

And a good place to insert it in functions.php is just above the line number that gets quoted in the error:

* @param bool $trigger Whether to trigger the error for deprecated functions. Default true.
	 */
	if ( WP_DEBUG && apply_filters( 'deprecated_function_trigger_error', true ) ) {
		debug_print_backtrace(DEBUG_BACKTRACE_IGNORE_ARGS);
		if ( function_exists( '__' ) ) {

This will show you the call stack, which should give you some idea of where it’s coming from. For me it was actually in header.php and not a plugin at all. Remember to take it out again afterwards!

I am a real novice where do I enter the wp_get_current_user(); please. My issue was “you are using outdated element it is depreciated since version 4.6.” am I on the same issue page as you guys lol. I am on WordPress 4.7.1. Thank you
