 * Hi i have set up this plugin for my site.
    But after making it active the site
   stops functioning. It gives me this kind of error. `Fatal error: require_once()[
   function.require]: Failed opening required 'PLS_FUNCTIONS_DIR/core.php' (include_path
   ='.;C:\php\pear') in F:\www\realestate\wp-content\plugins\placester\blueprint\

   Can you please guide me what i need to change.

 * Tell me more about the server being used. What version of wordpress and php. 
   What other plugins are installed? What theme are you using?

 * Ahh, yes, Advanced Custom Field is a known plugin that has an incompatibility
   problem with the Placester plugin. How are you using the plugin?

 * Hi zaptest,
 * It turns out that the incompatibility with Advanced Custom Fields is usable with
   the Options Page addon available at [http://www.advancedcustomfields.com/add-ons/options-page/](http://www.advancedcustomfields.com/add-ons/options-page/)

 * Matt,
 * Can you please explain the steps for the ACF Options Page to work? Or have there
   been any more developments to make the two plugins more compatible?
 * As far as I can tell, it doesn’t. It requires ACF to work, but ACF is conflicting
   with Placester.
 * Please let me know your thoughts. Thanks!

 * I just had to install the addon from the ACF developer for the Options Page. 
   Then everything is resolved. This was a solution that a customer came up with
   and it has worked for everyone I have worked with on it.
 * What problem are you having?
