Mediatama Store

Hi, I just start a new prestashop instalation dan set auto update on, At first 3 weeks there was nothing going wrong, but now I noticed, everytime I update / click on my product tab, like price, association, there are warning like below when I want to save. And also, the bullet / mark of my previous choice of associations in missing. Any idea why this happens ? and how to fix it ? Thanks.

Mantap gan, Sudah dibeli dan dipasang di online store kami mediatama.id. Pelayanan ok, respon cepat. Kalo ada masalah tinggal diskusi saja, langsung ditanggapi. Daripada susah2 utak atik sendiri, mending beli saja dari agan ini, tinggal pakai.
