Problem with draft pages

Hello
I have this problem when open draft page:

Not Found
Sorry, but you are looking for something that isn’t here.

Warning: include(/home/admin/domains/mysite.com/public_html/wp-content/themes/industrial-20/searchform.php) [function.include]: failed to open stream: No such file or directory in /home/admin/domains/mysite.com/public_html/wp-content/themes/industrial-20/index.php on line 35

Warning: include() [function.include]: Failed opening ‘/home/admin/domains/v/public_html/wp-content/themes/industrial-20/searchform.php’ for inclusion (include_path=’.:/usr/local/lib/php’) in /home/admin/domains/mysite.com/public_html/wp-content/themes/industrial-20/index.php on line 35

I have this problem since I upgraded to version 2.3.2.
Can help me please?
P.S. if i open the page with mi IP and with IE i see the page, the page is draft, but if anyone clik on link to draft page see the error, maybe problem with .htacces?
