Today Really Simple SSL 2.5.25 has been released. This latest version of Really Simple SSL includes a number of minor fixes and has been tested with WordPress 4.9.4. A number of typos and upper/lowercase text have been fixed. On multisite installations, the ‘switch mixed content fixer hook’ option was not visible. This has been addressed in version 2.5.25, multisite installations can now switch the hook on which the mixed content fixer fires. We have also tested the plugin with Gutenberg.
