i was working on a plugin that can find some special url in wordpress page contents and then if matching URL found then change that url automatically to another url like without giving backlink benfit to that site.

for example :
if i have defined a site that start with www.site2.com
and i wants to redirect this to another site www.site3.com

now pluging will convert url fount www.site.com on page to www.site.com/og.php=www.site2.com now if user clicks this url this will be redirected to www.site3.com

after inslalling and activating plugin found urls are converting but when i clicks them getting error "/og.php" file not found

And when i have tried to open option page to add more url or changing some settings on page
it's giving me error "you do not have permission to access this page"

below you can check my codes for both pages

it's giving me error "you do not have permission to access this page"

The error means you don't have permission from the admin side.

Another words there's nothing wrong with the code it's means that you didn't configure plugin permission in the beginning for this plugin to function/work.

how to resolve the permission issue....?

how to resolve the permission issue....?

I didn't expect you to say that because it's on the WordPress platform. I can't believe you are creating a plugin and not know where to set the permission?

Here is the link:

http://codex.wordpress.org/Changing_File_Permissions

on Local host

Fatal error: Call to undefined function get_option() in D:\wordpress\InstantWP_4.1\iwpserver\htdocs\wordpress\wp-admin\st_auto_affiliate_links_options.php on line 8

on online hosted site getting
