php - 404 error due to .htaccess -

i copied our live project sub directory. when trying run it, it's showing 404 error. did required changes in .htaccess file, still showing /publish/index.php page not found.

i checked file , folder exist , have 755 permissions. don't know why showing 404 error.

here .htaccess file code.

rewriteengine on rewritebase /var/www/site/serp/httpdocs/ rewriterule ^robots.txt /robots-development.txt rewriterule ^robots.txt /robots-development.txt rewriterule ^index.htm([^/]+)/$ /publish/index.php?lang_value=$1 [nc] rewriterule ^index.php$ /publish/index.php [nc] rewriterule ^index.htm$ /publish/index.php [nc] 

note:- cant restart apache server. can't add in apache conf files.

your rewritebase seems wrong should relative path documentroot:

rewriteengine on  rewriterule ^robots\.txt$ robots-development.txt [l,nc]  rewriterule ^index\.htm([^/]+)/$ publish/index.php?lang_value=$1 [nc,l,qsa]  rewriterule ^index\.php$ publish/index.php [nc,l]
