When you do a fresh install of prestashop, just after it finishes you need to rename the “admin” directory. The problem is that with the last two installs we did (as part of WebIngenia), we ended up with a blank/empty/white webpage. The only way to solve it was to clear the opcode cache from APC.
So, if you encounter the same problem, you know what to do, you just need to clear the APC opcode cache and continue the install.
BTW, sorry for not having properly maintained this blog recently. Not enough free time. I’ll release an updated version of the TC65 guide pretty soon.
