Hello.

I have installed the dolibarr. And now i will change to read only for the file. But where to do that? as i still get the message, even to have tried give 444 as it is read only on one.com. But i can’t

How to make it read only? And remove the error message?

What server OS? Are you SuperUser (or do you have comparable rights)? Path to …/htdocs ?

It is on a subdomain in root. I have full access on the ftp.
I don’t know the server os. it is one.com webhotel.

I am superuser on the dolibarr system yes.
