Just wanted to let you know that if you have the issue that your server does not support PHP 5.x or but runs on 4.4.x... There is a way to use WP. Use version 2.8.6, and you can use the AddThis 2.3 plugin also, but an important function is missing. The name of the function required is:
This function can be found in wordpress/wp-includes/formatting.php in WP version 3.1.4 on line 2857. Copy the entire function and then paste it at the end before the ?> tag in the 2.8.6 version of formatting.php. Done.
Also if your version of 4.4.x does not run Json you will have to install it via Pear and Pecl. Here are some basic instructions. Requirements are PHP-Devel, Pear and GCC:
Type this into your terminal app
sudo pear install pecl/json
This should download and install json 1.2.1 and install it.
Now you have to find your php.ini file and add the following line:
Then restart Apache
Hope that this will help some of you.
