Title: Problems with Captcha Last modified: June 27, 2017 --- # Problems with Captcha * [ntenhoedt](https://wordpress.org/support/users/ntenhoedt/) * (@ntenhoedt) * [8 years, 11 months ago](https://wordpress.org/support/topic/problems-with-captcha-2/) * Hello, * I’ve asked this a while ago. There are still some problems with the captcha not displaying. If you put in a number and try to send the message, the number disappears but it is still required. * The website is : [http://www.tep3d.com/contactformulier/](http://www.tep3d.com/contactformulier/) * I asked the hosting and they told me they support PHP sessions. * Hope you can help! * Best, Nikos Viewing 13 replies - 1 through 13 (of 13 total) * Plugin Author [Guido](https://wordpress.org/support/users/guido07111975/) * (@guido07111975) * [8 years, 11 months ago](https://wordpress.org/support/topic/problems-with-captcha-2/#post-9266351) * Hi Nikos, * Are you able to edit your plugin for a test? * Please open file vscf-form.php Add this directly ABOVE “// The shortcode”: * ``` if(!session_start()) { echo 'no session'; } else { echo 'session started'; } ``` * Go to your contact page… which notice do you see? * Guido * Thread Starter [ntenhoedt](https://wordpress.org/support/users/ntenhoedt/) * (@ntenhoedt) * [8 years, 11 months ago](https://wordpress.org/support/topic/problems-with-captcha-2/#post-9266596) * Hello Guido, * If I paste this text before the shortcode the plugin deactivates itself. Maybe the code is not correct? * Best, Nikos * Plugin Author [Guido](https://wordpress.org/support/users/guido07111975/) * (@guido07111975) * [8 years, 11 months ago](https://wordpress.org/support/topic/problems-with-captcha-2/#post-9266893) * Hi. * Strange.. did test it myself before my previous response.. can you activate plugin again? * It should like this after adding it: * ``` $_SESSION['vscf-rand'] = isset($_SESSION['vscf-rand']) ? $_SESSION['vscf-rand'] : rand(100, 999); if(!session_start()) { echo 'no session'; } else { echo 'session started'; } // The shortcode ``` * Guido * Thread Starter [ntenhoedt](https://wordpress.org/support/users/ntenhoedt/) * (@ntenhoedt) * [8 years, 11 months ago](https://wordpress.org/support/topic/problems-with-captcha-2/#post-9268826) * hello Guido, * I was using the code that I got in the mail as a reply, therefore it didn’t work! It now says: Session started. Is that a good thing? * Best, Nikos * Plugin Author [Guido](https://wordpress.org/support/users/guido07111975/) * (@guido07111975) * [8 years, 11 months ago](https://wordpress.org/support/topic/problems-with-captcha-2/#post-9268980) * Hi Nikos, * Dutch? * Dat betekent dat sessies inderdaad wel ondersteund worden op je server.. dus dan is het probleem iets anders. Meestal een conflict met een andere plugin ( of je thema), die ook gebruik maakt van sessies. Welke plugins gebruik je nog meer naast Yoast? * Je zou je plugins 1 voor 1 kunnen de-activeren en telkens een test bericht sturen, om er zo achter te komen of en welke plugin het probleem veroorzaakt. * En anders, toch maar overstappen op een andere contact plugin.. * Guido * Thread Starter [ntenhoedt](https://wordpress.org/support/users/ntenhoedt/) * (@ntenhoedt) * [8 years, 11 months ago](https://wordpress.org/support/topic/problems-with-captcha-2/#post-9272684) * Hello Guido, * yes I am dutch but I figured that in english it would also be helpful for others. * I’ve deactivated all the plugins and the one that caused trouble was the Yoast plugin, which you already mentioned. Does it happen more often with this specific plugin? * Plugin Author [Guido](https://wordpress.org/support/users/guido07111975/) * (@guido07111975) * [8 years, 11 months ago](https://wordpress.org/support/topic/problems-with-captcha-2/#post-9274215) * Hi, * There was another user who had the same problem in the past, but I currently have no idea how to solve this. My session has it’s own unique name, so maybe Yoast closes all sessions including mine at a certain point. That’s the only explanation I currently have.. * Will keep you informed. But if you are able to ask Yoast yourself, please go ahead. * Guido * Thread Starter [ntenhoedt](https://wordpress.org/support/users/ntenhoedt/) * (@ntenhoedt) * [8 years, 11 months ago](https://wordpress.org/support/topic/problems-with-captcha-2/#post-9285140) * All right, thank for you the help!

Is there a way to just add a text string instead of a number to the captcha. The form field that reads Enter number 835: is not going to make sense for most web visitors. Or at least change the label. I’m using this on a page and not as a widget. Is it possible to add any parameters to the shortcode that’s not used directly on page (not widget)? If more than one parameter, are they separated by commas? Thx. - This reply was modified 8 years, 8 months ago by [Lisa](https://wordpress.org/support/users/berelsonhotmailcom/). * Plugin Author [Guido](https://wordpress.org/support/users/guido07111975/) * (@guido07111975) * [8 years, 8 months ago](https://wordpress.org/support/topic/problems-with-captcha-2/#post-9543928) * Hi, * It’s build to display a randon number. Only thing you can do is change the label. Example: * ``` [contact label_captcha="Please enter %s"] [contact label_captcha="Please enter %s here"] ``` * Guido * ps. please create your own topic next time, because I don’t check old topics frequently.
