 * Hi there !
 * I think there are some conflicts with 4.0 and other plugins.
 * i have this error message :
 *     ```
       Warning: preg_replace() [function.preg-replace]: Unknown modifier '#' in /wp-content/plugins/hashbuddy/includes/hashbuddy.php on line 91
       ```
   
 * The warning happens with the new release of WP Idea Stream from [@imath](https://wordpress.org/support/users/imath/)
   when we click on the details of an idea.
 * I’m also checkin the problem on the other side.
 * Any fix on this issue ?

 * Hi [@qobalt](https://wordpress.org/support/users/qobalt/),
 * Replyed on my blog to make both plugins work fine together.
 * I don’t think it’s specific to WP Idea Stream. The problem is appearing when 
   a post/page/custom post type is containing a link with an anchor. eg:
 * `<a href="http://site.url/#anchor">Link</a>`

 * Hi [@imath](https://wordpress.org/support/users/imath/).
 * Can you please direct us to the exact resource. I looked on your blog but unfortunately
   I don’t understand French. I would really like to use hashbuddy but can’t because
   of this problem.
 * Thanks.

 * hi [@profusion](https://wordpress.org/support/users/profusion/)
 * Well to avoid the “conflict” with hashbuddy on WP Idea Stream parts, you can 
   do the following :
    1/ copy the code of this gist : [https://gist.github.com/imath/cca1ce09f38243364269](https://gist.github.com/imath/cca1ce09f38243364269)
   2/ create a file `wp-idea-stream-custom.php` at the root of plugin’s directory
   so that you have : `/wp-content/plugins/wp-idea-stream-custom.php` 3/ Paste the
   content of the gist into the created file.
 * The other option is to deactivate WP Idea Stream, of course 🙂
