Yes, I was just coming to report this as well. Digging into the files that get generated, in _admin.scss there is the following code:
input[type=checkbox]:checked::before {
content: url(“data:image/svg+xml;utf8,%3Csvg%20xmlns%3D%27http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%27%20viewBox%3D%270%200%2020%2020%27%3E%3Cpath%20d%3D%27M14.83%204.89l1.34.94-5.81%208.38H9.02L5.78%209.67l1.34-1.25%202.57%202.4z%27%20fill%3D%27#{url-friendly-colour($form-checked)}%27%2F%3E%3C%2Fsvg%3E”);
}
Comparing this to the old developer version from GitHub I’ve been using on previous sites, that same section of code in the _admin.scss is:
input[type=checkbox]:checked:before {
color: $form-checked;
}
If I replace the longer version above with this shorter version, then the checkboxes are visible in the Dashboard again.
I don’t write plugins and my php knowledge is shaky at best, so I can’t tell where or how this new version is being generated – but hopefully this gives the devs enough info to fix this.
Oh, and you also have to get the plugin to regenerate things once you’ve made that change. After you change that bit of the code and saved it in _admin.css, then go back to the plugin, change one of the colors, and save it. This seems to rewrite whatever is screwing up the checkboxes.
Hello – I’ve had this trouble too. I was able to get the ‘ticks’ to show by simply uploading the /admin-color-schemer/ folder found in /wp-uploads/ from an older version of the plugin (v1.0.) Then regenerate the colors and you should be good.
The same happened to me and replaces the admin.scss file as artsgirl mentioned above, following the path:
wp-content/uploads/admin-color-schemer/_admin.scss
Thank you for your help!
