So I've updated CataBlog to version 0.8.1, this is a crucial upgrade because it fixes a memory leak which caused the plugin to take up more and more system memory over time. Everyone using CataBlog should upgrade to this latest release unless they want their blog to eventually run out of system memory.
The memory leak was due to the plugin's construct method, which copied the $wpdb object into the plugin class. Now CataBlog is using the global version of $wpdb in all methods which access the database. Is this something that could have been fixed with a destruct method? Instead of playing around with the code I decided the most pertinent thing would be to immediately fix the issue and offer an update to all users. Hope this fixes any issues you had with CataBlog, enjoy.
