thank you so much dear James..
my error is gone!!!!
i’m so worried about this two days! but now it’s solved.
i tried to fix the pluggable.php and login.php and config.php but the problem come from another place. exact here: wp-content/plugins/w3-total-cache/inc/functions/compat.php there was just a blank before <?php, then i erase that and finish.
thank you again Sir.

Thanks for attention dear allisonplus
i add the “W3 Total Cache 0.9.4.1” plugin and after two or three days i see that error.
the important notice is that is this website is belonging to the company and i’m just a simple employee!!!
