Hi Sam,
Sorry for late reply to this,
Oh, it seems like your admin profile is set to use Tiny-mce editor, but the `developer` user account is set to default, so the system will see what you set the default editor from your backend > Easyblog > setting > general > composer .
For the composer, we call it readmore block, you can click on the "add block" button from the composer and select readmore block, check my video link :
