Regarding Post Title text colour – not working

Hi Shamack,
The reason for this is because the styles in your theme override the styles from this plugin. You would need to create a custom font control in the admin area. Here is an example of what you would need to do:

1. Log in to your WordPress admin area and go to: Settings > Google Fonts
2. Click create new font control and give your font control a name e.g Post Title and click the Create Font Control button. (If no other custom font controls exist then it will take you straight to the add new control screen)
3. Once you have created your new font control enter the following text in the Add CSS Selectors input box: .entry-header h2.entry-title a (Press tab after each selector)
4. Click the Save Font Control button
5. Visit the customizer and you will see your new font control which will allow you to control the post title

Hope that helps. Please let me know how you get on

Sunny
