Hello and thank you for your assistant so fast.
I tried to follow your indication literally, but I have for a small problem...
I created well the file which I placed on my server :
If I understood well, it is necessary to replace " install.txt " by " install.sh "?
Then to put the chmod in 777 ?
And finally, I have to go on this page with my sailor(browser)...
Now, me cross that I missed something that ? I do not know.
Saddened for my ignorance and my English
