# 4.0.1 : syntax error admin/summary.php

 * `Parse error: syntax error, unexpected '[' in /data/wordpress/wp-content/plugins/
   wp-fail2ban/admin/summary.php on line 59`
 * Upon upgrading to 4.0.1 all pages on the site became blank. I enabled DEBUG in
   the config and found wp-fail2ban was the cause. I deleted the plugin from the
   filesystem and my sites came back up. I then attempted to re-install through 
   the web UI. Upon attempting Network Activate, WP won’t activate and reports the
   error above.
 * I’m unsure if that bug in summary.php is what caused all pages to stop working(
   seems unlikely since it’s just an admin page)
 * Once the summary page bug is fixed I’ll see if I can reproduce the bug that causes
   all WP pages to go blank

 * The curse of PHP 5.3 strikes again…. That should be fixed now in 4.0.2.
 * That file is only loaded when you’re looking at the admin area – I can’t see 
   how it would break anything else.

 * 4.0.2 fixed this bug. I did not encounter the site-wide issue I was seeing before
   either so that was either also fixed, or there was some other issue going on.
 * Thanks!
