jordanjay29 I have the doubt that I wrote at second post of this topic, I can change the title if you want just to solve this issue ?
During the installation, I had to give 777 (not 755) permissions to the whole httpdcs folder&files, maybe this could happen to someone else and if so, it would be fine to restore the permisions after the installation.
Currently I'm with all the httpdocs folder with 777 permissions. I'm checking different permission folders just now.
