After many tries I have been able to install CB 1.9 on my site.
Problems are due to my hosting (his name is FREE in France and it is free but with many restrictions).
Now, the only problem to solve is the database fields that are wrongs. The Database Fields test return problems like I say on my first post.
Is there any way to verify or modify manually fileds tables on PhpMyAdmin to solve definitely this problem ?
Thanks...
