SSL Insecure Content Fixer v2.7.0 has just been released. This release fixes responsive images loaded from data attributes; fixes call to undefined function `hash_equals()`; and doesn’t run the fixer on a WooCommerce download request.
Test page failure on old PHP versions
Version 2.6.0 changed how the HTTPS detection test secured itself from unauthorised access, by calling the relatively new PHP function
hash_equals(). This lead to test page failures on websites still running obsolete versions of PHP (basically, anything earlier than PHP 5.6). This version adds support for those websites.
WooCommerce download requests
There’s been a long-running problem that some people have been seeing with SSL Insecure Content Fixer and WooCommerce downloadable products. I have never been able to replicate the problem, and there’s always been a simple fix, so I’ve been basically ignoring it. However, it’s just not going away, so I’ve added some code to hopefully prevent the problem. If it doesn’t, someone is bound to tell me on that support ticket 🙂
You can update to the latest version from your WordPress plugin admin page. Here’s the full changelog for SSL Insecure Content Fixer.
