 * Hi,
    I’m trying to activate the plugin on linux hosting where I have a lot of
   wordpress websites and it gives me an error when trying to activate the plugin:
 *     ```
       Warning: require_once(/home/dvirh/public_html/mydomain.com/rojo/wp-content/themes/rojo/plugins/meta_slider/inc/slider/metaslider.class.php) [function.require-once]: failed to open stream: No such file or directory in /home/dvirh/public_html/mydomain.com/rojo/wp-content/plugins/ml-slider/ml-slider.php on line 24
   
       Fatal error: require_once() [function.require]: Failed opening required '/home/dvirh/public_html/mydomain.com/rojo/wp-content/themes/rojo/plugins/meta_slider/inc/slider/metaslider.class.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/dvirh/public_html/mydomain.com/rojo/wp-content/plugins/ml-slider/ml-slider.php on line 24
       ```

    thanks!

 * Hi dvirhazout,
 * Are you using the premium ‘Rojo’ theme by any chance, or is it coincidence that
   you have ‘rojo’ in the path?
 * The theme, I believe, already has Meta Slider installed. Try deleting both the‘
   wp-content/plugins/meta_slider’ and the ‘wp-content/plugins/ml-slider’ folder,
   then install a fresh copy from your plugins menu.
 * Regards,
    Tom

 * You’re right. I use the rojo premium theme which I see now already has the plugin
   built in.
    but I can’t seem to see the menu of the meta slider in the dashboard
   but I guess it’s a question to the theme author.
 * Thank you so much!!

 * No problem 🙂
 * If you don’t get a response from the author then feel free to email the theme
   to me (I won’t use it on a public site), and I’ll see if I can work out whats
   up. It did look like Meta Slider had been modified by the theme author when i
   saw a screenshot for it in that theme.

    Tom

 * I dropped the plugin from the theme dir along with the line requesting the plugin
   from the functions.php file and then installed the plugin and it’s perfect.
 * Thanks again,
    Dvir
