Thank you so much for help James ! It has been resolved because of you my friend. Have a great week buddy.

I did it with the same result. I tried also replace all includes directory with all files but had the same result. Still with this troubleshot. Do you have some another tip or alternative attitude for resolving this issue?

Thanks James for renponse, i tried it, everything as you recommended, also replacing the file functions.php but its look still the same.

Here is that code in the link 3737 can you check it out?
trigger_error( sprintf( __('%1$s was called with an argument that is <strong>deprecated</strong> since version %2$s! %3$s'), $function, $version, $message ) );

Thanks for your time !

Thanks for your tip but it doesnt work. Still have a blank page. Do you have any better idea?
