I am not sure if this is template specific problem but I've had this problem before with another Shpae5 theme wherein I always had to add </br> every time I needed an extra line BUT as soon as I switch to Visual editor and save it, it deletes all my manually inserted </br> .argggh!
This is becoming a simple but frustrating problem in formatting. My clients just gives up on updating their site just because of this since they do not want to deal with using the text version of the editor.
Thanks in advance gain
