thanx esmi … your suggestion worked. but i think .. there is no need for saving “.htaccess” file. specially for mine case. i removed every file except wp-content folder.
and one more thing i can’t find “.htaccess” in my blog, i also have searched if file is hidden.
Hello i am newbi, so i forgot to disable the plugins and i started upgrade , so that message was showing, when i googled about it, some one suggested for removing .maintenance file, when i removed then this problem is coming . nothing is showing in my blog please help.
