Title: [Plugin: Visual Form Builder] Security check – WordPress error Last modified: August 20, 2016 --- # [Plugin: Visual Form Builder] Security check – WordPress error * [Frank](https://wordpress.org/support/users/frankvancaspel/) * (@frankvancaspel) * [14 years, 4 months ago](https://wordpress.org/support/topic/plugin-visual-form-builder-security-check-wordpress-error/) * My form at [nssl.nl/sign-up](http://nssl.nl/sign-up) has spontaneously stopped working. When I’m logged into WordPress I can complete the form just fine, but when I’m logged out I get a nearly blank page titled ‘WordPress error’ which says only ‘Security check’. * A few days ago the form worked just fine, and I haven’t changed anything in terms of plug-ins since then. Right now I’ve upgraded to the most recent versions of both WordPress and the plugin, but that didn’t solve the problem. * I’m now going to try to make a new version of the form and see if it has the same problem, but if anyone has any thoughts in the meantime please let me know. * [http://wordpress.org/extend/plugins/visual-form-builder/](http://wordpress.org/extend/plugins/visual-form-builder/) Viewing 8 replies - 16 through 23 (of 23 total) [←](https://wordpress.org/support/topic/plugin-visual-form-builder-security-check-wordpress-error/?output_format=md) [1](https://wordpress.org/support/topic/plugin-visual-form-builder-security-check-wordpress-error/?output_format=md) 2 * [TroutMojo](https://wordpress.org/support/users/troutmojo/) * (@troutmojo) * [14 years, 2 months ago](https://wordpress.org/support/topic/plugin-visual-form-builder-security-check-wordpress-error/page/2/#post-2583354) * Yep, I found 3 ‘Security Check’ lines from Visual-Form-Builder.php file. I named them 1st, 2nd and 3rd. It seems that it goes to first one everytime (does not matter if I’m logged in as admin or not) * So visual-form-builder.php line 2306 * Let me know if I can help more. * Cheers, A * [twitmytwat](https://wordpress.org/support/users/twitmytwat/) * (@twitmytwat) * [14 years, 2 months ago](https://wordpress.org/support/topic/plugin-visual-form-builder-security-check-wordpress-error/page/2/#post-2583355) * having a similar issue what is interesting is that the site works when NOT using www.

Things on my side haven’t changed since my last post though: both the form on [http://nssl.nl/testsignup2](http://nssl.nl/testsignup2)( cached) as well as [http://nssl.nl/signuptest](http://nssl.nl/signuptest) (cached) continue to work. So I have no idea what caused the original problem. * However: I’m currently actually no longer using the form plugin, because sign- ups for the tournament have closed. * Good luck! * [twitmytwat](https://wordpress.org/support/users/twitmytwat/) * (@twitmytwat) * [14 years, 2 months ago](https://wordpress.org/support/topic/plugin-visual-form-builder-security-check-wordpress-error/page/2/#post-2583358) * hmmm… I tried deleting the plugin and it turns out it didnt have to do with the form after all but wp super cache. * [TroutMojo](https://wordpress.org/support/users/troutmojo/) * (@troutmojo) * [14 years, 2 months ago](https://wordpress.org/support/topic/plugin-visual-form-builder-security-check-wordpress-error/page/2/#post-2583359) * As I said earlier I haven’t installed any cache plugin so my problem remains. * [tamerax](https://wordpress.org/support/users/tamerax/) * (@tamerax) * [14 years, 2 months ago](https://wordpress.org/support/topic/plugin-visual-form-builder-security-check-wordpress-error/page/2/#post-2583363) * my site did this today.
