I did the 7-1.4 upgrade today to address the security concern. It went in cleanly with no errors, but when I visited one of my view pages, the view wouldn't return at all. I tried both 7-1.4 and the current dev version, and no dice.
I'm using a SOLR index to create a view. I went into that index and tried disabling / enabling it, clearing / reindexing it, and nothing helped. As soon as I reverted back to 7-1.3 everything immediately started working again. Nothing registered on the error logs in Drupal either.
Anyone run into something similar?
