Similar to yesterday’s update, today I pushed out wpGForm v0.30. This version addresses an unusual problem which prevents the custom confirmation CSS from loading properly.
In some cases, it appears that a plugin or theme, through the use of a filter (likely the_content or wpautop), was inserting paragraph tags into the content which by itself isn’t a problem, however when enabled, wpGForm adds a custom CSS block to style the form during processing, so the CSS definition portion of the content ended up with paragraph tags in it. This results in CSS which won’t parse correctly and of course it never styles the form. I have updated the plugin to generate the CSS definition as a single line of text where it previously spanned several lines for readability purposes.
The update should appear on your Dashboard shortly and is also available from the WordPress Plugin Repository.
