 * I’m running into trouble downgrading this plugin from version 3.5 to 3.3. The
   reason is that versions after 3.3 require PHP 5.4+ and that’s not something we’re
   able to support at the moment (RHEL6 servers). I need to hold all sites at 3.3
   until we can get them migrated to some servers that will support PHP 5.4 (a process
   we’re expecting to take about a year). We unfortunately didn’t catch the new 
   PHP requirement until after the upgrade.
 * After downgrade, I’m seeing errors like:
 * > PHP Parse error: syntax error, unexpected T_STRING in [site-path]/wp-content/
   > plugins/redirection/models/match.php on line 72, referer: [page-url]
 * I have no (good) way of reverting databases to previous backups at this point,
   since it seems site owners lived with this broken for a while before reporting.
   Thoughts?

 * The error looks like the plugin hasn’t been downgraded, and contains a file with
   PHP 5.4 code.

 * I would agree, which is strange since I did the downgrade via WP-CLI (which should
   replace all plugin files).
 * Ultimately I got it working again by downgrading one step further to 3.2.1, which
   should work until I can get these sites all migrated to newer systems. This can
   be marked resolved.
