I'm just getting familiar with and downloaded prestashop to Windows in xampp. When loading prestashop, the install php page says that it needs php 5. The xampp version I'm using is 1.7.7 which has version PHP 5.3.8 (VC9 X86 32bit thread safe) + PEAR. Wordpress works fine so I know php is working. I'd rather use this xampp version if I can without having to install again. What am I missing to get prestashop running?
I'm looking to use for selling a wide range of unique items, and I'm sick of wasting time with ebay.
Is prestashop considered the best open source solution these days for this task?
