CAPTCHA NOT WORKING WITH PHP7

Hi try the following instructions see if they help you.

Hello and thank you for your reply.
I’ve already tried that.
Just to let you know, I’m receiving a “this image cannot be displayed because it contains errors” message when trying to access just the captcha image. And, after some tests, realized that it’s because PHP (7) version.

By the way, there isn’t anything about it in server logs.

Hi, thank you for reporting back. I will submit a ticket to the plugin developer.

Thank you

I just installed PHP 7.0.3 on my CentOS 7 development server.

The CAPTCHA works.
Make sure your PHP7 has the GD Library installed, because at first it did not work, then I had to add the PHP7 GD Library package. After installing that, the CAPTCHA worked.

I have found some code to fix for better php 7 compatibility. It is in the captcha image class. It will only cause a problem if your server is set to display errors that are just warnings. I will release an update soon

I just uploaded the new version. Is it fixed now?

Breaks captcha on PHP 5.4.45-0+deb7u2 giving the false url of /contact/#FSContact1 instead of correct thank-you page redirect after submitting form.

Logs reveals an error
PHP Fatal error: Class 'securimage_ctf' not found in /var/www/blog/wp-content/plugins/si-contact-form/includes/class-fscf-process.php on line 977

The line in is class-fscf-process.php (captcha with PHP sessions)
$img = new Securimage_ctf();

Worked before the update, nbothing else is changed.

The line 976

$img = new Securimage_ctf();

in plugins/si-contact-form/includes/class-fscf-process.php should be

$img = new Securimage_Captcha_ctf();

since the class Securimage_ctf doen not exist anymore in captcha/securimage.php, it is replaced with class Securimage_Captcha_ctf

Got it fixed ??

Sorry for the inconvenience, I will fix that ASAP

Should be fixed in version 4.0.41
