Access phppgadmin from another computer?
The /etc/apache2/conf.d/phppgadmin.conf configuration file by default keeps anyone but localhost from accessing PhpPgAdmin.
Add a line that makes a new allow rule for your IP, so it looks something like this:
<Location /phppgadmin>
Order deny,allow
Deny from all
Allow from [Your client IP]
</Location>
By the way, this kind of question is probably more appropriate for stackoverflow's sister site serverfault.com
This is an apache (or web server) issue. You're phppgadmin directory has a .htaccess file disallowing EVERYONE except localhost.
You need to either set it to Allow ALL or Allow (insert IP here)
I know this is an old question but since i stumbled on it trying to fix the "Failed to load resource: the server responded with a status of 403 (Forbidden)" error while trying to access phpPgAdmin from another computer and the given answers didn't work for me, I wanted to share my solution.
Ubuntu: 17.04; phpPgAdmin: 5.1
Solution: Comment out Require local in /etc/apache2/conf-enabled/phppgadmin.conf and restart apache (sudo service apache2 reload)
<Directory /usr/share/phppgadmin>
<IfModule mod_dir.c>
DirectoryIndex index.php
</IfModule>
AllowOverride None
# Only allow connections from localhost:
# Require local
<IfModule mod_php.c>
php_flag magic_quotes_gpc Off
php_flag track_vars On
#php_value include_path .
</IfModule>
<IfModule !mod_php.c>
<IfModule mod_actions.c>
<IfModule mod_cgi.c>
AddType application/x-httpd-php .php
Action application/x-httpd-php /cgi-bin/php
</IfModule>
<IfModule mod_cgid.c>
AddType application/x-httpd-php .php
Action application/x-httpd-php /cgi-bin/php
</IfModule>
</IfModule>
</IfModule>
</Directory>
/etc/apache2/conf-enabled/phppgadmin.conf
