SSL Insecure Content Fixer v2.1.4 has just been released. This release fixes inline CSS background images, and adds a French translation.
Many thanks to Houzepha Taheraly for the French translation. Other translations are also warmly welcomed! NB: please note that translations for this plugin are now hosted on WordPress.org, so sign up there to add your translations.
Some WordPress plugins and themes add background images to your website through inline CSS. SSL Insecure Content Fixer can now clean up mixed content errors with inline CSS when the fix level is set to Content, Widgets, or Capture. As always, only use the highest level you need for fixing your problem; lower fix levels use less server resources.
The settings and test pages now show a tick or cross indicator, telling you whether WordPress can successfully detect HTTPS. This can help you know whether you need to fiddle with the HTTPS detection settings. Just because this plugin recommends a different setting, that doesn’t mean you need to pick it — e.g. if you already have a plugin or some code in your wp-config.php that handles HTTPS detection, then you can leave those settings alone in this plugin.
Sometimes the HTTPS detection settings can trigger conflicts with other plugins. To help undo that when it happens, you can now define
SSLFIX_PLUGIN_NO_HTTPS_DETECT in wp-config.php to prevent conflicts while you set this plugin back to defaults.
You can update to version 2.1.4 from your WordPress plugin admin page. Here’s the full changelog for SSL Insecure Content Fixer.
