 * Hey guys,
 * Are you by any chance using the WP Editor plugin (which has been deprecated a
   long time ago)? There’s a known conflict with that plugin, which we are fixing
   in the next update that’s going out soon.
 * If you are, I’d recommend you to simply deactivate the plugin for now. You can
   actually even get rid of it completely since the functionality of that plugin
   has almost been fully integrated into WP Core years ago.

 * Yes sir, this solved the problem. We won’t be needing WP editor anymore anyway.
 * Thanks!!!
