[SOLVED] Unable to install the application

Hello community.

Can not install the product with a PostgreSQL database.
In the main.php file, I have the error: "A technical error has probably occurred due to a bad network connection".
Probably it comes from PHP-XML (Module DOMDocument) extensions. Indeed, when I delete this extension, no problem, but I can next step.

Can you help me ?

Centos 7 / Apache 2.4 / PHP 5.4 / PostgreSQL 9.2
ProjeQtor : 6.4.4

Thank you for your request for a supplement.

You will find in attachment the Apache error log.
Regarding, the log ProjeQto.log into the../files/logs/projeqtor_${date}.log, but the directory is empty.

Your application is increbible/fanstatic !

The directory is empty
[smatou@ProjeQtor logs]$ ls -altr

We had no problem with Centos / Apache / MySQL / PHP !
If I uninstall PHP-XML the error message disappears, but I can not go to the next step

Hello,

I have just reinstalled my server from scratch.
Same issues.

Thank you for telling us quickly that ProjeQtor works well with this stack ?
Regards.
