After I try to activate the developer mode I see the page reloading but after that it seems that I'm not longer logged in. But this happens only when I run the odoo server (an Ubuntu 14.4) in the subdomain mode with this parameter (dbfilter=^%d).
if I click on the Logo, what is the only thing that remains, I will get back to the login menue.
Seems to me as it is a bug?
What do you see when try the database selector: subdomain.domain.tld/web/database/manager ?
Also my regexp looks like ^%d$ , I don't know if the $ sign makes a difference.
@Erwin I see all the database in the databse selector that have an identical beginning of the db-name. Eg. If my domain is demo.domain.tld and I have also a db called demo_xx I cann see this one too. I can't imagine that the $ sign at the end of your dbfilter regexp makes a different? But I should try: on the difference dee: https://www.odoo.com/de_DE/forum/hilfe-1/question/domain-based-db-filter-6583
The $ seems not the issue in this case. The reason why I'm asking is that I experience also strange behaviour with logouts when I'm using Odoo without dbfilter, means while having access to a list of several databases. A new login by selecting the appropriate database from the list solves the problem. I definitely do not have any problems as long as dbfilter identifies exactly 1 database which should be the case in production mode anyway if you want to avoid different kind of problems.
I don't remember if it makes a difference if you properly log out before selecting another database and then activating the developer mode. But I have to confess that this issue doesn't bother me too much, I have many more serious problems to solve :-)
