What to do the feeds box is showing that you have failing feeds, like so:
Check for errors
When you get this error display check the following for any errors related to PureClarity feeds:
Server error logs at /var/log/<nginx or httpd>/ on the filesystem
Magento logs at <magentoroot>/var/log/ on the filesystem
cron_schedule table, to see if there are any errors against any row with the job_code "pureclarity_core_scheduled_feed"
Check the "pureclarity_state" table to see what value is logged in the row with the name "last_feed_error"
If you have version 6.1.0 or later, you can use the logs page to access PureClarity logs instead of the general logs locations listed above.
