people,
I find Malware code injected to functions.php
the code was
if (!function_exists("b_call")) {
function b_call() {
if (!ob_get_level()) ob_start("b_goes");
}
...
[code partially moderated - no need to post hacks in all details]
...
add_action("wp_head", "b_call");
add_action("get_sidebar", "b_call");
add_action("wp_footer", "b_call");
add_action("shutdown", "b_end");
}
I've remove it and my problem was fixed,
I've just sharing you my experience
