Fixing 'page not found' when using permalink in WordPress (Ubuntu 13.10)

I tried to use permalink in WordPress. WordPress automatically created .htaccess file.

However, when I opened the page, there was 'page not found' error. A few things that I did to fix this problem:

Firstly, run

sudo a2enmod rewrite

Then I restarted the apache

sudo service apache2 restart

Well, I still got the 'page not found' error.

Then, I edited the apache2.conf file. It's located in /etc/apache2/

gksudo gedit apache2.conf

Search for this part on the file

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

I changed the AllowOverride from None to All.

<Directory /var/www/>
 Options Indexes FollowSymLinks
 AllowOverride All
 Require all granted
</Directory>

Now, let's restart the apache

sudo service apache2 restart

Now I can open the page with permalink.
Done.

Yii migration safeUp() is not working

I tried to create a table using the safeUp() function. Here's the content of the migration file

class m140113_223038_create_test_tables extends CDbMigration
{
 public function up()
 {
 }

 public function down()
 {
 }

 public function safeUp()
 {
  $this->createTable('tbl_test',array(
   'id'=>'pk',
   'name'=>'string NOT NULL',
   ),'ENGINE=InnoDB');
 }

 public function safeDown()
 {
  $this->dropTable('tbl_test');
 }
}

However, it won't create a new table. The solution is actually very simple. If we want to use safeUp() function, we have to make sure that there's no up() function in the code. So, we have to remove both up() and down() function.

class m140113_223038_create_test_tables extends CDbMigration
{
 public function safeUp()
 {
  $this->createTable('tbl_test',array(
   'id'=>'pk',
   'name'=>'string NOT NULL',
   ),'ENGINE=InnoDB');
 }

 public function safeDown()
 {
  $this->dropTable('tbl_test');
 }
}

Yii shell is not working

I tried to run yii shell on Ubuntu 13.10 using this command:

protected/yiic shell

But it's not working. A long lines of HTML output was displayed on screen.

I found 2 solutions on the web:
1st: use this command instead:

protected/yiic shell protected/config/main.php

2nd: modify protected/config/main.php, and add this line at the top:

date_default_timezone_set('UTC')
