Make a copy of your website locally and test it. I am assuming there is either something wrong with your .htaccess file or the database.

Seems like your attachment rules are taking over your category rules(maybe because they don’t exist in your database).

Also, try replacing rewrite_rules with the _transient ones but do a database backup first.

Did you try default theme(with all plugins deactivated)?
Use debug bar plugin and see what is the query sql.

Do categories work with other permalink settings i.e /%year%/%monthnum%/%day%/%postname%/ ??

Are these rules with the patch applied from the ticket?

The first rules don’t seem to have category rules(maybe I’m missing something there) but the second rules contain category rules.

A URL to your site would also be helpful.

Pastebin rewrite_rules from options table

Change this to

$query->set('meta_key','oqp_guest_email');
$query->set('meta_value',$dummy_email);

to

$query->set( 'meta_query', array( 'key' => 'opq_guest_email', 'value' => $dummy_email, 'type' => 'string', 'compare' => '=' ) );

See this ticket https://core.trac.www.ads-software.com/ticket/14645 for more information.

Edit:
Try
$query->set( 'meta_query', array( array( 'key' => 'opq_guest_email', 'value' => $dummy_email, 'type' => 'string', 'compare' => '=' ) ) );

Resetting the plugins folder

Admin Bar Minimiser plugin is only compatible with 3.1

or maybe you can use recent posts widget.

A little sample to get you started:

d = new Date();
if( d.getHours() > 5 && d.getHours() < 18 ){
alert('day');
} else {
alert('night');
}

Okay he fixed it, the new version will be up in 15 mins.

The submit_button() is a 3.1 function, I’ll tell Victor(plugin developer) to back compat it for 3.0

Just wait for the next update.

Move the ‘$comments = …’ to the while loop.

<?php while ($featuredPosts->have_posts()) : $featuredPosts->the_post();?>
<?php $comments = get_comments( array( 'number' => 2, 'post_id' => get_the_ID() ) ); ?>

Disable ZdStatistics plugin and check your site

or you can create a sprite( or separate two images ) for opened and closed quotes and use them as background using CSS
for example: p:first-child and ‘p:last-child’ or any other selectors.
