404 with post name permalinks

Question

So, I have a pretty common problem - I recently upgraded to Ubuntu Trusty Tahr from Precise, and I had to upgrade apache as a result. Now, my wordpress site is accessible, but I am unable to access any pages within my wordpress site.

So, for example, www.asjweddingsandevents.com works fine, but www.asjweddingsandevents.com/about gives a 404 ("about" is a page in wordpress). I've tried resetting the permalinks from "page name" to "plain" - when in the "plain" form, the pages are accessible via the page_id=-style link (e.g. http://www.asjweddingsandevents.com/?page_id=10), but when I set them back to "page name", they are inaccessible again.

I've double-checked that the apache rewrite mod is enabled (it's being used for other sites on the same server), and I've also double-checked the permissions of the .htaccess file, which are 666. The .htaccess file has the following contents:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

I'm not super fluent in wordpress configuration, and even worse, I'm not really an apache ninja, so some help on what I'm doing wrong (or, given this is a general error, how I can troubleshoot what's going wrong) would be much appreciated.

Answer 1

I was able to figure out the problem, and for the sake of posterity, I'm posting the answer here. Basically, the new apache2.conf file that was added when I updated my web server had the following lines in it (my document root is /var/www):

<Directory /var/www/>                                                           
        Options Indexes FollowSymLinks                                          
        AllowOverride None                                                      
        Require all granted                                                     
</Directory>

I replaced the AllowOverride None line with AllowOverride all, restarted apache, and the permalinks now work.

Hopefully this will aid someone in the future with a similar problem.
