have you check the hosting requirements?

internal server errors are usually due to incorrect or unsupported settings in .htaccess files, usually means that your host does not support mod_rewrite

The host support mod_rewrite !!!

But the technical support you would give me the prerequisites of CMS oxwall.

And they think the problem is. Htaccess file which is not good.

I can give my ID and password for my account of my hoster to an administrator to see which way the problem.

Thank you for your help.

The chances are they do not allow the following mod_rewrite setting in the root .htaccess 

Options +FollowSymLinks

some members have reported that changing the above line to the following fixes things

Options +SymLinksIfOwnerMatch

I have change the line in the root .htaccess and there is alway the error =/

what happens if you comment out that line with a ##

so it will look like

## Options +FollowSymLinks

or

## Options +SymLinksIfOwnerMatch

Same error

Change way upload be zip file and unzip after upload completed.
deleted old oxwall .

I have already do that 3 times since one week !!

The problem come from .htaccess I think !

if you remove or rename the .htaccess file what happens then?

When I have rename or remove, there is that ! =/

I can give you by MP :
- FTPs idents
- Mysql idents

For see where come the problem !

the problem is with the .htaccess file, and it means that it is a server config problem, your host should look to see what info is being wriiten to the error log.

also just to be certain can you post the contents of your .htaccess here?

OP, try checking into your error_log file as initial error will most probably be recorded there and would slightly help you with identifying the reason of your problem.

.htaccess :

Options +FollowSymLinks
RewriteEngine On

AddEncoding gzip .gz
AddEncoding gzip .gzip
<FilesMatch "\.(js.gz|js.gzip)$">
  ForceType text/javascript
</FilesMatch>
<FilesMatch "\.(css.gz|css.gzip)$">
  ForceType text/css
</FilesMatch>

RewriteCond %{REQUEST_URI} .*/http-bind
RewriteRule (.*) /http-bind [L]

RewriteCond %{REQUEST_URI} !^/index\.php
RewriteCond %{REQUEST_URI} !/ow_updates/index\.php
RewriteCond %{REQUEST_URI} !/ow_updates/
RewriteCond %{REQUEST_URI} !/ow_cron/run\.php
RewriteCond %{REQUEST_URI} (/|\.php|\.html|\.htm|\.feed|robots\.txt|\.raw|/[^.]*)$  [NC]
RewriteRule (.*) index.php

What about error_log? What happens when you use default .htaccess file?

Where iserror_log ? Don't find it.

When I use default .htaccess there is :
Title: 500 Internal Server Error

Message:
"The server Encountered internal error or misconfiguration year and WAS Unable to Complete your request.

Please contact the server administrator, and inform em null@easy-hebergement.fr of the time the error occurred, and anything you might Have done that may Have Caused the error.

More information about this error may Be available in the server error log. "

can you ask your webhost to locate the error_log for you as this would tell us what is causing the error

Salamoz, have you already checked with your hosting company whether your server meets our requirements and whether mod_rewrite is enabled?

What is the URL where you are trying to install Oxwall?
