I understand everyone's frustration with this issue. Please understand that my full-time job must come before this, as well as many other things.
I do fully intend to update WordPress Firewall 2 as soon as possible. I've had some fixes and a few new features already done, literally for months now. I know I said it would be much, much sooner; I know a lot of time has gone by. Regardless of how much I can get done in the next 1-2 weeks, I will release an update, so you all can see at least some progress.
Please continue to report issues - I do check this forum, I am aware of the most annoying problems, and I do intend to have at least the serialize/unserialize issue fixed in this update.
A final note, the serialize/unserialize errors are not fatal errors. WF2 will continue to operate, even when encountering these errors. If you have WF2 installed, even if you get these errors, the plugin is still protecting your site.
