Hi Support, My web is www.trainingcompany.in.th Now I was complainted a lot from our customer that they could not add new lists. Then I tried to add new lists by manual in admin area. I cannot also add new lists. If we add new lists. The old one page4(the prior page) will disappear. Total lists that I can add is only 80 lists. If I add more. The first list will be disappear. I already upgraded to version 1.8.3 and use child theme to operate website. Regards, Surachai
