Wordpress error after upgrade "cannot redeclare" + "eval()'d" -

getting error after forced wordpress upload (i working in database when @ 1 point of time got alert - while on backend, 1 alternative upgrade newer available version):

fatal error: cannot redeclare _421736532() (previously declared in /home/user/domains/mydomain.com/public_html/wp-content/themes/twentyelevenmodified/header.php(68) : eval()'d code:1) in /home/user/domains/mydomain.com/public_html/wp-content/themes/twentyelevenmodified/header.php(68) : eval()'d code on line 1

the above when seek mydomain.com

when seek mydomain.com/wp-admin/, redirected wp-login.php , getting next error:

fatal error: cannot redeclare _421736532() (previously declared in /home/user/domains/mydomain.com/public_html/wp-login.php(80) : eval()'d code:1) in /home/user/domains/mydomain.com/public_html/wp-login.php(80) : eval()'d code on line 1

pulling hair out trying different things since 5 hours now. help appreciated.

edit: after testing, found function.php file correctly calling function twentyeleven_header_style() , problem coming after calling function. it's next function phone call causing problem. if know next function !!!

wordpress doesn't utilize functions names. deactivate plugins or rename plugins folder.

if doesn't work it's coming theme. rename theme folder wordpress revert default (assuming default theme exists).

it sounds purchased theme or plugin obfuscated code , it's using eval() run , making phone call home.

wordpress eval
