Assisted Animemike in installing Sphinx Search today and decided to install it myself - I got the same error when being redirected to search results (not the CMS). I've applied this fix which stops the error from occuring:
Open ./packages/vbsphinxsearch/coresearchcontroller.php
Go to line 611, which should be:
Code:
$index[] = implode(", ", $sphinx_index['sphinxindices']);
Above this add:
Code:
if ($sphinx_index['sphinxindices'] == NULL)
{
continue;
}
Save and upload coresearchcontroller.php and the errors should go away
