Registration form conflict with Wordfence plugin

Thanks Stiofan — I’m going to look into integrating the recaptcha into the registration form, and implementing Askimet for comments.

I noted in a different thread back in May someone listed Wordfence as being currently compatible with GD, so I’m not sure why my install kicked out the error as other threads elsewhere have suggested that it was an update to the core WP and a subsequent WF update back in 2013 that started the problem of the missing arguments from a custom registration form.

Perhaps there is a setting in WF to disable the reg form scan. I’ll look into that also.

Other threads I found seemed to indicate a similar error occurring with various captcha plugins which would expand the scope of the compatibility problem beyond WF to potentially include any component that interacts with custom reg forms.

Would it make sense to modify the custom form in some way so that the arguments WF is missing get supplied by the form, even if they are not strictly necessary for the creation of users by GD?

Paolo made a good point about the performance load of security plugins like WF, but WF does a lot more to monitor, scan, and block attacks than just registration and comment spam, and I’m uncomfortable not using it or something very similar.

Excellent! That seems to have resolved the issue. I can now successfully register new users with Wordfence enabled.

I am also going to look more into adding the recaptcha to the reg form, and will enable Askimet for the comments.

As Stiofan suggested, it appears that it was indeed an issue related to changes in the latest PHP version – so absence of an issue might either mean that the host has not upgraded to php 5.4, has not forced the non-affected account to use 5.4 instead of an earlier version, or has done something different with their configuration that did the same thing as the code Stiofan recommended adding to the functions.php file.

I’m glad for the simple fix!

I’ve seen in the past with the reporting provided by Wordfence, just how often sites get probed. I’ve particularly seen a real surge right after I put up the domain. It seems to trickle off for the most part once the bots figure out that it’s not a soft target.
