We had the same problem. The configuration the field "Reply-To E-Mail" was not filled. This field is mandatory for creating new forms now, but in our forms created with earlier versions of this plugin the Reply-To was empty. This caused an error during sending the e-mail (the data still was stored in the database).
After filling this field all continued to work perfectly again.
@lueenkowode We also had a 500 error problem, solution which helped for our website: https://wordpress.org/support/topic/error-500-after-latest-update?replies=5#post-8771719

Can someone tell me why when completing a form on our website and click submit we get an error message saying
Security check - referral does not match this site??
The form then won't go through at all?
Any help would be grateful
The problem was in PHP version i had 5.3... when i switched to 5.5 everything works fine.
Tnx for support.
Hello LTS,
This typically happens when a form is being generated from one URL, but displayed on another URL, as most servers/wordpress installs will see a security threat with this. Here is some documentation about the error to help get you off in the right direction: http://classic.vfbpro.com/faq/security-check-referal-does-not-match-this-site/
Thanks!

Hi,
Great plugin.. are for now using the free version and have a question for the notification email that we can sent to the user.. can I in this email enter / use the information that the user have just added to the form, like: Hi "name" and we are looking forward the the meeting on "Date" at "time"
Is this something we can do and how?
Thanks
Jacob
I really like your plugin! But again I foud some SERIOUS bugs caused by some funny approaches in your plugin's code and since I needed to make it work immediately, I solved it for you and because you are making this plugin great (in other parts) I've decided to share the solutions with you...
Bugs I've found when I was locating the source of problem for why aren't emails stored to DB:
a) In your DB table you have a column date_submitted in table YOUR_WP_DB_PREFIX_visual_form_builder_entries which has a DATETIME as type. I don't know what magic DB you are using, but this type usually(and especially in MySQL/MariaDB) means format (PHP): Y-m-d H:i:s and that's it ... line 308 in YOUR_WP_INSTALL/wp-content/plugins/visual-form-builder/includes/email.php which is currently
'date_submitted' => date_i18n( 'Y-m-d G:i:s' ),
Should be replaced with
'date_submitted' => date( 'Y-m-d H:i:s' ),
If you do not change this, entries on sites with non-mysql-like-localized-datetime will not be stored in newer WP versions!
b) You also have to have some magic IP addresses, because you've defined table column ip_address in the previously mentioned table as VARCHAR with a length of 25 - in my world, there is IPv4 - max character length 15 and IPv6 - max character length is usually 39 but can reach up to 4-something, so 50 should be safe. Also there is no reason to escape html in IP before putting it into DB - that should be done after recieving it from DB...
The initial bug is on line 699
in YOUR_WP_INSTALL/wp-content/plugins/visual-form-builder/includes/visual-form-builder.php
Which is currently
ip_address VARCHAR(25)
But should be
ip_address VARCHAR(50)
ALSO! In next update you should add this query in the update process:
'ALTER TABLE ' . $wpdb->prefix . 'visual_form_builder_entries CHANGE ip_address ip_address VARCHAR(50)'
If you do not change this, entries of users with IPv6 will not be stored in newer WP versions!
Also please fix another very serious bug - the email-header thing I've described (solution included!:) in HERE ! Thanks ! :)
We recently updateg VFB to the latest. After updating when someone clicks submit we get the following error. I will also note that testing other contact form plugins all work fine it is only the VFB latest that is giving this error. The form notification is sent however we get this error:
Fatal error: Uncaught exception 'phpmailerException' with message 'Invalid address: ' in /home/homer/public_html/wp-includes/class-phpmailer.php:946 Stack trace: #0 /home/homer/public_html/wp-includes/pluggable.php(352): PHPMailer->setFrom('', '') #1 /home/homer/public_html/wp-content/plugins/visual-form-builder/includes/email.php(401): wp_mail('', '', '<!DOCTYPE html ...', Array, '') #2 /home/homer/public_html/wp-content/plugins/visual-form-builder/visual-form-builder.php(1935): require('/home/jbidegain...') #3 [internal function]: Visual_Form_Builder->email('') #4 /home/homer/public_html/wp-includes/plugin.php(524): call_user_func_array(Array, Array) #5 /home/homer/public_html/wp-settings.php(411): do_action('init') #6 /home/homer/public_html/wp-config.php(89): require_once('/home/jbidegain...') #7 /home/homer/public_html/wp-load.php(39): require_once('/home/jbidegain...') #8 /home/homer/public_html/wp-blog-header.php(13): require_once('/home/jbidegain...') #9 /home/homer/public_h in /home/homer/public_html/wp-includes/class-phpmailer.php on line 946

I am having the same error on my site. My forms were working. My site is hosted by GoDaddy.
Hello Nmasters!
I am sorry it took me a little while to get back to you on this. You can definitely do some templating for emails but this feature is only available in our Pro version, pulling values and defaults from various places.
In this case I think the pro version would be a good way for you to go.

Hello Jave.web,
Wow thank you so much, and thank you for taking the time to provide this feedback, for your belief in our plugin and helping us improve it. This information will be passed immediately off to our developer for consideration in the next release.
What version are you using? Is this the free version?
Thank you,
Joseph
VFBPro Support
Well I am posting here, so yes it is the free version available from the wordpress.org repository :)
Thank you very much for your interest ! :)
Hello Bluerayconcepts and drhurd,
First and foremost which version are you both using? That being said MOST errors like this are caused by the php version on your server being to low for both WordPress and VFBPro, please make sure you are running php 5.4 or better. This is especially common on some of Godaddy's older legacy servers where they are not able to update the php version for you at all.
Hope this helps.
