Bypassing errors trick i used during failed upgrades

[xpindia]

I was trying to upgrade from 1.6.7 to 1.6.14 prestashp, and it always failed giving some ajax or other funny error and also failed to restore back.

 

Deleted the cache>cachefx folder, and in 1click upgrade disabled backup options, and since i have a dedicated server

i increased the server performance to highest.

 

It upgraded without any errors and also very fast to Prestashop 1.6.14.

 

Hope it helps some soul in trouble.
