Blocks do not appear ...

Hmmm..

There are a number of places the module could be falling over. To start with, you could try chucking in some debugging into the module code. Find this section in the function relevant_content_block:

      //Get the terms for the current page using a little reusable wrapper function
      $terms = relevant_content_get_page_terms();

      //If there are no terms, not a lot of point in continuing
      if (empty($terms)) {
        return;
      }

and change it to

      //Get the terms for the current page using a little reusable wrapper function
      $terms = relevant_content_get_page_terms();

echo "Node Terms are...";
print_r($terms);

      //If there are no terms, not a lot of point in continuing
      if (empty($terms)) {
        return;
      }

This should print out the text "Node terms are..." followed by an array of the current node's terms at the top of the page. If nothing at all comes up then the block isn't being viewed. If just the text comes up then your node doesn't have any taxonomy available. If the whole shebang comes up then we're good to move on.

The other problem could be to do with the terms getting excluded due to vocabulary filtering. Try putting in a little more debugging code...

      //Again - if there are no terms, no need to continue!
      if (empty($terms)) {
        return;
      }

      //Create a node exclusion list - this will exclude the currently viewed node - if applicable.

change that to this:

      //Again - if there are no terms, no need to continue!
      if (empty($terms)) {
        return;
      }
echo "We still have terms!!";

      //Create a node exclusion list - this will exclude the currently viewed node - if applicable.

Please post back with the results :-)

I have the same problem with Liliplanet, though i see you continued your troubleshouting in private. I see that liliplanets webpage no longer suffers from the problem, so could you please make the solution public, if there is one ofcourse. I use postgresql if it helps. thanks

Check if you are using Node Breadcrumb module, after turning this off the Relevant content module appeared, now I have another problem... breadcrumbs are not the way I wont them anymore.

@wexy my node breadcrumb module is disabled by default, but I still can't view the rc block as well.

Also, the rc_cck module is throwing errors as well. When it throws this error, the cck field won't show up on the node creation page. The error says "invalid argument supplied for foreach() in relevant_content_cck.module on line 226".

As promising as this module would have been, these errors are does not make worth the effort.

Please, help fix with a patch.

Thanks.

@Liliplanet Please, make the solution public. Thank you.

I have Relevant Content working great. As soon I installed Node Breadcrumbs, the Relevant Content blocks will not appear even if I remove the default restriction to appear on node/* pages only.

UPDATE:
As soon as I disable the Node Breadcrumbs module, the Relevant Content blocks appear again.
