Befor run install.php, i change right to config.php (for www-data only read and exec).
I write manualy parameters in config.php.
And run install.php! It is work!

I leave permission 500 for config.php, it doesn't pass Folder Permissions check.
If leave it writable, got error when connecting to DB, how can I solve that?

Hello everyone,
I am having the same bug as I am trying to install it on a raspberryPI.
It is weird that no matter what I type on the browser on install.php, the value seems to be written directly into the file, but on the next page, where the psql authentication fails, those values seem to be empty.

Thanks!

Hi,

i have the same Problem as littlewine.
I want to install wifidog on Debian 8.5, but Wifidog can't access the database.
I get the same message as limulidae.

When i look into the config.php all values are saved correctly.
I installed phppgadmin and I can connect to the database without problems.
So its neither a php nor a DB problem.
If there is any way to get wifidog to work with this bug pls tell us ;)

Thanks

Simple but working work-around. I changed the config.php values manually to those created on postgresql and hardcoded them into install.php too.
I just wanted to see at the moment if I could pass that step and I did after all, now I am stuck on the next one (see the other open issues)! :)

Answer 8 · 2016-09-06T12:35:42.000Z
