Hi There,
I have bought pro theme on 4/10/18. Firstly I download free item and then i upgrade for pro. After i upgrade the pro Item the home page is changing to a new one. Suddenly on 5th of October the home page is back to the free theme(before i upgrade). My admin pasword also change to adminx due to cannot login. Also when I change my Product Category the produst Catogery is missing from my Home page. Kindly assist me. Your kind assistant is much appreciate. Thank you https://www.syahira-store.com
