I have upgraded to php 5.4 and Zenphoto version 1.4.6
Captcha is no longer working for me.

The web host reverted me back to 5.2 (which i would rather not do) and replied...

'your script a may not be fully compatible with PHP 5.4 which is why the CAPTCHA fails to load when the site is set to that PHP handler. You may need to see if there is an upgrade available for your custom script which brings additional support for PHP 5.4'
Is it just me?
thanks for any guidance

zp_catpcha and reCaptcha work both fine even under PHP 5.5.9.

As always without any error log entry we will most likely not be able to help.

hello I have an error....

[14-Aug-2014 14:14:22 Europe/London] PHP Fatal error: Call to a member function cropImage() on a non-object in /home/wwwsss/public_html/upg/zp-core/lib-Imagick.php on line 289

Sorry, no idea. Sure imagick is actually working correctly on your server? Did you try GD?
