Firefox can't open php file from apache2 server on localhost

[s_ø]

Dont think you should reinstall yet.
When you upgraded to lucid, you also upgraded php to version 5.3.
Look at this page about migrating from 5.2 to 5.3 http://www.php.net/manual/en/migration53.php
One of the changes is to the php.ini files. http://www.php.net/manual/en/migration53.ini.php

I am runnning 5.2 in Karmic, so I cant help you with specifics of the php.ini files.
but look around in /etc/php5/apache2/ for the php.ini files
In the .ini files kook for this or similar

; Enable the PHP scripting language engine under Apache.
engine = On

engine needs to be On to work.
This directive can be set from 'anywhere' so look in httpd.conf, .htaccess files for this php_flag engine off

NOW WORKS: deleting cache, history solved the issue
I have the same problem and only happens on Firefox, I've tried with Konqueror and works fine, why?

EDITED: FIXED

Are you the OP?

cleaning the cache did not solve the issue for me. I tried with a clean profile, same issue.

try to comment out the bold lines. (I think the syntax has changed to the semicolon ; for comments.

# To re-enable php in user directories comment the following lines
# (from <IfModule ...> to </IfModule>.) Do NOT set it to On as it
# prevents .htaccess files from disabling it.
<IfModule mod_userdir.c>
<Directory /home/*/public_html>
php_admin_value engine Off
</Directory>
</IfModule>

this solved the issue

I've had a similar problem - try replacing localhost with 127.0.0.1
it seems everytime you upgrade the localhost mapping gets lost....

Hi Makrie, comment all lines with # or replace these lines in mods-available/php5.conf, and adds these last two lines:

sudo nano /etc/apache2/mods-available/php5.conf

<IfModule mod_php5.c>
# <FilesMatch "\.ph(p3?|tml)$">
# SetHandler application/x-httpd-php
# </FilesMatch>
# <FilesMatch "\.phps$">
# SetHandler application/x-httpd-php-source
# </FilesMatch>
# To re-enable php in user directories comment the following lines
# (from <IfModule ...> to </IfModule>.) Do NOT set it to On as it
# prevents .htaccess files from disabling it.
# <IfModule mod_userdir.c>
# <Directory /home/ruso/public_html>
# php_admin_value engine OFF
# </Directory>
# </IfModule>
AddType application/x-httpd-php .php .phtml .php3 .html .xhtml
AddType application/x-httpd-php-source .phps
</IfModule>

sudo /etc/init.d/apache2 restart

It worked for me!

Hi,

It's funny. I have spent many days to figure out why I can't used localhost while using 127.0.0.1 and hostname can work nicely.....

Anyone can have an explanation on this?

Thanks a lot.

I also had this problem. I reloaded Apache2 and it was still there. Tried clearing the Firefox Cache as suggested in another post. This did not work for the tools menu. My profile was on an NT file system. After I emptied the Cache directory in my profile using normal file system access the problem was gone.
