  • Syntax fixes (various)
1.4.6 2012-04-29
  • Increased memory available to Wordfence to 256M during security scans, configurable in wordfenceConstants.php
  • Improved memory logging during security scans. Current memory usage is now shown on the far right of filenames while scans occur.
1.4.5 2012-04-27
  • Bugfix - fixed bug that caused Wordfence menu to dissapear.
1.4.4 2012-04-27
  • WordPress Multi-site support added. Currently in Beta. Tested with subdomains, not subdirectories, but it should work great on both.
  • Main changes are moving menus to the Network Admin area, preventing individual blogs from enabling the plugin and dealing with database prefix issues.
1.4.3 2012-04-26
  • Improved diagnistic information on binary and regular API calls for better debugging.
  • Changed ticker to only show activity with level < 3
1.4.2 2012-04-26
  • Email to send security alerts to is now configured at the same time an API key is entered.
  • phpinfo is emailed along with activity log when user requests to send us activity log so that we can see things like PHP max execution time and other relevant data
  • Now writing individual files to activity log during security scans for better diagnostics.
  • Login security message.
  • Updated readme.txt FAQ and description.
  • Fixed bug where sites with self signed SSL security certificate never start scan because cert fails security check.
  • Increased API curl timeout to 300 for slower hosts that seem affected during URL security scans.
v1.4.1 2012-04-25
1.3.3 2012-04-23
  • Made real-time server polling more efficient.
  • Entering your API key now automatically starts your first scan. Was causing some confusion.
  • Link to forums added for free customer support.
1.3.2 2012-04-23
  • Reduced the number of database connections that Wordfence makes to one.
  • Modified the memory efficient unbuffered queries we use to only use a single DB connection.
  • Removed status updates during post and comment scans which prevents interference with unbuffered queries and makes the scans even faster.
1.3.1 2012-04-23
  • Fixed a bug where if you have the plugin "secure-wordpress" installed, you can't do a Wordfence scan because it says you have the wrong version. This is because secure-wordpress trashes the $wp_version global variable to hide your version rather than using the filters provided by WordPress. So coded a workaround so that your Wordfence scans will work with that plugin installed.
1.3 2012-04-23
  • Minor fix to point to the correct binary API URL on the Wordfence cloud servers.
1.2 2012-04-23
1.1 2012-04-21
