When I try to upgrade a site through the UI, with about a couple hundred nodes and half a dozen users, the module returns a success message but fails in the background. The system log returns "Upgraded ________ (processed 0 items total)" for each module, returning zero even for those that have many records. After that, it returns "Source ID ____: Missing bundle for entity type node" for every node that I have. In the end, it upgraded not a single content node, user, content type, taxonomy vocabulary or term, nothing at all.
While testing migrations from 7.x to early 8.x's I'm sure there was a re-roll option when I went back to the upgrade page that appears to be missing on current 8.x version, did I dream this option or am I looking in the wrong place?
I'm not sure why, but suddenly we can't get update data any more. I did a search and tried the most common solutions--clearing the cache_update table, increasing the timeout, etc. but nothing seems to work.
Are there any log files I can look at to try to figure out why this is happening? I don't see anything in Drupal's recent log messages or in the Apache error_log.
I thought maybe it was a firewall issue but when I go to updates.drupal.org, I get the message that my IP isn't being blocked.
