I installed WP robot 4.0.2, In replace keywords area, I input apple|iphone|100, then I updated the campaign. After that I goto control panel page, and re-edit the campaign again. The replace keywords area change to apple|iphone|100|, It automatically add a "|" at the end of phase. I delete it and update again. but the system add "|" again. With "|" at the end of the phrase, the replace function doesn't work. It won't replace the keywords. Does anyone know why? Help, Thanks..
