   or string given in /usr/home/grupoandoca.com/web/wp-content/plugins/if-menu/if-

 * Hi Sandra,
 * Thanks for letting me know about this
 * From my tests or other site owners, If Menu seems to work fine on WP 4.9.2. Was
   a plugin or theme updated when this error started showing up? Other developers
   can change If Menu visibility rules and this may cause the error
