– You can insert the subcategories by clicking on ‘Add Category’ and choosing any category name from the list in parent category. If you select root as parent category, then you create a main category.
– Create a subcategory is mandatory and required!

Depending on the “Permalink Settings” it’s possible for some pages that the categories urls are not accessible.
To fix this problem you should go to update the .htaccess file which is exised under wordpress top directory.

Normaly if you click on categories you will get something like this:

you can upadte your the .htaccess file as follows:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteRule ^97-revision-v1/?([^/]*)?/?(.*)$ /index.php?pagename=odlinks=$1=$2 [QSA,L,R,NS]

Questions and Examples of Use

Frequently Asked Questions

Q. Why the main site gives me the 404 or Not Found error message or I cannot see the “Submitt a link”?

This usually occurs only when using a custom permalink structure (like /%category%/%postname%/).
This is a .htaccess 404 error message and you should update your .htaccess file in the WP root directory.

Normally you should not edit the htaccess, the Permalink link will be detect by plugin automatically.

Please install the CURL module for PHP.

    Hi Mohammad,
    What a great plugin.  I love it!  Thanks!
    Unfortunately, when it is installed, it messes up the list of categories in the text editor.  See screenshots.

    As categories are an important part of my blog architecture, and being able to select them quickly and easily when adding a new post is important, this is VERY inconvenient.
    This is the category list should look:  http://rebtinfo.info/images/cat-good.jpg
    This is how it looks after installing OD Links:  http://rebtinfo.info/images/cat-bad.jpg
     Any suggestions?
    Thanks v. much for your help.
