i just upgraded wordpress 1.5 to latest version 188.8.131.52.
I followed the instructions from thread http://wordpress.org/support/topic/33189
The frontend is working properly but if im trying to access the backend (wp-amin) i always get the message
Fatal error: Call to undefined function: __() in /wordpress/wp-admin/index.php on line 3
i searched the forum for this issue and somebody suggested to re-upload the wp-includes folder, which i did. but it doesnt work.
any ideas how i can solve the problem?
thanks for replying
