& instead of "space character"

bump ??

I’ve this problem sinc I’ve migrated my Blog.

Migrated from where to where, and how?

From 1&1 to Web4all.

Basic migration: copy / paste the DB & FTP files.

Site URL? Sounds like a character encoding issue; you need to talk to the host.

Is web4all real cheap? Or free? Either one is always a problem. See Recommended WordPress Web Hosting

They told me good things about this host. Customer service is very competent. It’s not a free hoster.

I reinstalled WP with the last version, and it’s good now ??
