Error in my_thread_global_end():1 thread didn’t exit
i uploaded the wordpress 2.6
after that, i configured the wp-confiq.php
then, i went to installation page.
and i saw this error on last line of the page.
i’ve installed it completely, but i have this
error on every page of my wordpress, even login page!
and the pages don’t work perfectly.
