There seems to be an issue for any members who have less than admin privileges where they do not have formatting option and the text they write is displayed (in the editor) as white... It seems that you're not actually writing anything until you realise it's all there when you highlight it.
Here's a screenshot
The plugins running are:
- Select Advanced Custom Fields
- Advanced Custom Fields
- Custom Fields for WordPress
- Easy Add Thumbnail
I had a feeling that Jetpack was causing the issue, but disabling it did nothing.
Any ideas on how I can fix this?
