 * After I installing the plugin and activate it and I go and choose the user I 
   want to restrict. There on that page is this error:
 * “Fatal error: Call to undefined function mb_convert_encoding() in /home/cnoctavi/
   public_html/wp-content/plugins/restrict-author-posting/restrict-author-posting.
   php on line 145”
 * Instead of the possibility to choose the restricted category…
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Ffatal-error-2761%2F%3Foutput_format%3Dmd&locale=en_US)
