actually that things happend afer i install that quickstart template bro, so here's the simulation
1. I download the quickstart package
2 I extract then run it at my localhost using xampp
3. I fill the name, email, name of page ,etc
4. I fill the database info
5. I delete the installation folder
6. then after it i press button go to site but that problem show up
so actually i did not do anything to that page so i think i shouldn't give you my backup cause i don't change anything,
