PowerCMS 102 Installation Wizard error

Hello,
I have created a very simple page (index.php) in a directory named "powercms" in my cpanel "public_html" directory.
Everything is fine when it comes to create a content, a database etc...
I have uploaded all the site files (mine plus the ones created by the WA extension) to be sure not to forget some.
When I run the diagnostic page I get the following error :
"Files and directories cannot be created. Verify the PowerCMS directory has write permissions on your server.
Files cannot be created in the PowerCMS/Connections directory. Please ensure that directory has write permissions on your server."
I've tried to chmod 777 my powercms directory and even (transciently) my public_html home dir... with no avail.
I am sure that a lot of people have had the same error.
Can anyone be of help ?

Hello,

For those who are experiencing the same issue.
1 - CMS Builder MUST be installed in the root directory of the web site. It is not evident in the documentation.
2 - the root directory MUST be 777 during installation (in my case public_html). Don't forget to get it back to a more standard 750 for example.
3 - the Connections directory MUST be 777 too.

And then, miracle, the installation runs.

After the installation, get Connections directory permissions back to 755.
The "files" directory created in root during installation must be chmod to 777.

Hope it helps
