These are my rules in .htacces file.
Options -MultiViews
# Turn Rewrite Engine On
RewriteEngine on
# Rewrite for login.php
RewriteRule ^Login login.php [NC,L]
# Rewrite for myaccount.php
RewriteRule ^Myaccount myaccount.php [NC,L]
# Rewrite for index.php
RewriteRule ^Home index.php [NC,L]
# Rewrite for post-images.php?post=xxxx
RewriteRule ^Postimages/([0-9a-zA-Z_-]+) post-images.php?post=$1 [NC,L]
All rules are working fine but the last one. post-images.php pages is perfectly working if i directly use the url but not with rewriteurl. its showing
Not Found
The requested URL /PostImages/135 was not found on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
Mmh, I tried to edit your RewriteRule and edited it to make this rule:
RewriteRule ^Postimages/(.*)$ http://www.yourwebsite.com/post-images.php?post=$1 [R=301,L]
It works for me, would u mind trying it?
