I am trying to figure out why my tag cloud is empty at mysavingcents.com. I posted a separate topic but now I have a specific question since i've narrowed down the culprit code.
The function wp_tag_cloud seems to return a null array even though i have 41 tags defined. From the codex, it looks like it's supposed to return an array of tags. I've been looking for the actual code to figure out what exactly the function is doing and why it is failing to generate an array. But it doesn't seem to be defined anywhere in the wordpress directory and I assume must be as part of a binary library.
If anyone knows or has access to the code, let me know. I suspect that I may have a corruption in my DB that is causing the wp_tag_cloud function to return NULL. I would like to see the code to see what variables it uses and help me direct where to look in the database tables..
