I’m trying to set up 21.0.0-alpha dev-version, but it just goes back to the start of the setup after it finishes:

1. /htdocs/install/: Dolibarr install or upgrade
2. setup…
3. /htdocs/install/: Dolibarr install or upgrade - End of setup  
Dolibarr administrator login ‘admin’ created successfully.

And after this /htdocs just throws me back to beginning of setup again…

Hello,

Dolibarr V20 is not out yet and V21 is even not ready.  
These versions are only for developers, no support on the forum.

Hi,  
thanks for your reply. Yes I noticed that, skipped back to v20, and it installed ok. Just wanted to check it out for new features…
