 * I have installed the optimize press theme, using wp-admin theme installation 
   menu (by uploading optimizepress.zip).
 * when i tried to activate the theme, it show a error like:
 * > Fatal error: Cannot redeclare duplicate_post_save_as_new_post() (previously
   > declared in /home/aperfect/public_html/wp-content/plugins/duplicate-post/duplicate-
   > post-admin.php:11) in /home/aperfect/public_html/wp-content/themes/OptimizePress/
   > admin/duplicate-post-admin.php on line 33
 * then i close my page. when i try to login again, it shows the same error and 
   admin panel doesn’t show.
 * how i can restore my previous theme? please help asap.

 * Your Duplicate Post plugin is conflicting with your new theme. Looks like you
   can only use one or the other – not both.

 * Try switching to the Twenty Ten theme by renaming your current theme’s folder
   in wp-content/themes using [FTP](http://codex.wordpress.org/FTP_Clients) or whatever
   file management application your host provides. You may need to access /wp-login.
   php to get this to kick in fully.

 * Please re-read the suggestion I gave above. You do not need to login to your 
   site to make the actual theme change.

 * No – you will be using Twenty Ten. You can switch to your old theme once you 
   have login access again.
