How to Permanently Fix WordPress Memory Exhausted Error in VPS

Recently, I upgrade my hosting account from a share hosting to a VPS system. I manage to get a very good deal from TurnKey Internet through their Black Friday 2011 sale.

After setting up the server, I started to move my wordpress blog to new VPS hosting. I restore the database & all the files. I checked the blog & everything function wonderfully well with a better speed.

I try to enter the admin page, but I was greeted with the following error message.

Fatal error: Allowed memory size of 33554432 bytes exhausted
(tried to allocate .....)

After a search through the internet, I found the solution by placing the following code in “wp-config.php” file under the wordpress directory.

define('WP_MEMORY_LIMIT', '64M');

However, I feel it is not practical to change one by one for all my blogs.

If you have VPS system with WHM/Cpanel, you can fix it permanently by

    1. Log in to WHM
    2. On the left-hand side menu, locate “Service Configuration” header
    3. Click on “PHP Configuration Editor”
    4. In the “Basic Mode” find the following line
Section Directive Info Value
Core memory_limit This sets the maximum amount of memory in bytes that a script is allowed to allocate. This helps prevent poorly written scripts for eating up all available memory on a server. Note that to have no memory limit, set this directive to -1. 32M
  1. Change the “Value” from “32M” to “64M”. Take note on the capital “M”
  2. I should fix all wordpress blogs in the same VPS

Google Page Rank Update, November 2011

On the 7th-8th November, 2011, Google was updating the Page Ranks. In my blog network, most of my websites going up in page rank. This is indeed a good news, although most of them up by only one point.

The page rank update came after Google update their Caffaine search algoritham which impacts 35% of the search results. Anyway, both are not related.

For those who are new to page rank, it is a metric between 0-10. 10 is the best while 0 is the lowest. The rank depends on many factors, mostly on-site SEO and backlinks to your website.
