Error http 500 to install PS 1.7 proccess 0% - 12% - 23%

[nicoguevara]

Good morning, I have a problem with the installation of PS 1.7.
When I am in the installation section error 500, the problem is that most of the time that error goes to the 0% process, but sometimes it passes that value and the error occurs at 12% or 23% of installation.
Please, for days I'm with this problem and I do not know how to solve it

 

The installation I'm doing on plesk 12, which uses IIS

You should try it with DEV mode enabled. That may tell you what the problem is. Probably you have a hosting with low memory than required, or some required extension is missing.

You can find how to enable DEV mode here https://www.prestashop.com/forums/topic/224525-how-to-turn-on-error-reporting-for-debug-information-blank-page-500-internal-server-error/

I search for a long time a solution to this very same problem. In the end everything I found was not working, but somehow, I discovered that it was the fastCGI module of my debian installation that created it. I changed fcgi to cgi and it's now working ok. It was easy on my server as I have this option available (I installed virtualmin to do all straightforward configurations).
