Hi,
Two months ago, I started using SilverStripe and I really enjoyed it.
As I use a shared web hosting and have no root access to the server, I installed it manually (without composer).
The site was running well.
But all of a sudden, after I made some changes in some js and ss files, the site refused to work normally displaying the following message (see below). I tried to undo my last changes but I could never recover from this situation.
Thus I tried to reinstall a backup of the files and the database I have made a few days ago. The message was still here.
Eventually I tried reinstalling a fresh SilverStripe from scratch (3.1.2 then 3.1.3 ) but the message is still here and I cannot access the administration part
The only thing I see is a textual site after the message and a final message telling the site installation was successful.

Here is the message after a fresh install

Installation terminée!

SilverStripe a été installé avec succès. (translation: SilverStripe install successful)

    Courrier électronique: jaaf64@zoraldia.com
    Mot de passe: ********* (password masqued but correctly displayed)

Vous pouvez commencer à éditer votre site en ouvrant le CMS (translation: you can start editing your site opening the CMS)

Pour des raisons de sécurité vous devriez supprimer maintenant les fichiers d’installation, à moins que vous n’ayez prévu de réinstaller le système ultérieurement (ce qui nécessite de se connecter comme administrateur, voir plus haut). Désormais, votre serveur n’aura besoin de droits de accès en écriture que pour le dossier « assets », vous pouvez donc les révoquer pour tous les autres dossiers. Faites clic ici pour supprimer les fichiers d’installation.

After clicking on the CMS link the message is still here and I can see a textual site like the screen capture presents (attachment) (the three small lights on a blue background are blinking)

I don't know what to do!

Hopefully you can disable the open_basedir. http://www.silverstripe.org/installing-silverstripe/show/20224)

Thank Willr,

I cannot access php.ini. Moreover, I discovered that using url like this one

mydomain.com/index.htm/admim instead of mydomain.com/admin, the site works normally.

The install doesn't dectect url rewrite mod (warning in requirement check before install) but my hoster tells me that the module is active on the web server and that the php technology used is dissociated from apache. Thus php doesn't know about the apache modules in use.

In fact it seems that url rewriting works but I dont know how to get rid of these index.php insides urls.
