Hello everyone,

my apologies for the performance of the website lately! After doing some much research I've located the problem:

the website is often using more technological resources of the hosting package at the hosting company then allowed.
E.g. the limit is 16mb of RAM usage, and lately we're using about 16,25mb, probably because of the size of data / posts of our site (and other info).
When this happens, you see the following page:

....page could not be located...
(and the books listed from Amazon.com)

It really is time to move to a different type of hosting, which is called VPS hosting for those of you who know what that is. It gives us more resources per month.

So, right now i am shopping around to see what we can find.

Onward and upward, :)

Tim
