can't upgrade to CB 1.4

you're right man, nothing has changed.

Do I have to delete all the files related to CB inside the admin folder and component folder through the FTP layer and then try one again to install??

Would be good to find out what is causing this.
Something on your environment.
Is there no access to your error log?

do you mean errors log on the server or on the backend of the site?

the server:
I haven't access to errors log of this part

this aftenoon the webmaster told me that to morrow he will have to install a new website with CB. He 'll see

Hi it's me again...

so we have checked the environment of mywebsite


Version de la base de données: 5.1.49-3
Collation de la base de données (dépend du jeu de caractères): utf8_general_ci
Version de PHP: 5.3.3-7+squeeze1
Serveur Web: Apache/2.2.16 (Debian)
Du serveur Web à l'interface PHP: apache2handler
Version de Joomla!: Joomla! 1.5.23 Stable [ senu takaa ama baji ] 04-March-2011 18:00 GMT

in the erros log nothing about this.

the only thing we cannot have successfully is the synchro between CB et CBsubs (this mod is blind , I can't go in any menu of this mod... (()

so what can I do???

may be a track for the solution...

I have installed on another website hosted on the same server (same environment) Joomla1.5.23 and then CB 1.4. It works fine. But....
112 zip
But when I try to install CBsubs main 112 zip nothing is achieved. I can't install Cbsubs

do you have an idea?

Sounds like an ioncube issue. Please ensure within PHP Information inside your Joomla install that ioncube is present (just search for "ioncube" on PHP info page). If you're adding ioncube through PHP.ini then please ensure a copy of PHP.ini is in your Joomla root AND root/administrator as it must be in both locations. If issue persists after doing this please PM backend login credentials as well as FTP credentials.
