Do you have the Enabled check box checked? Can you send me a screenshot of your settings? Thanks
Oh, I noticed just now that the end date is wrong and instead setting it in the next month I set it in current one and, so the end date was in the past. That is why it didn’t work. Now it’s visible again. Sorry for taking your time. Somehow months got switched on date picker.
The other thing is, that the message looks quite different then on the preview on settings page. It was always like that. But that’s a different story.
It looks different on the preview because in wp-admin it users WordPress CSS and on the front end it uses your theme CSS. At this point there is no way to control it, unless you override all CSS properties in your Custom CSS.
Oh, ok. Thanks for the explanation. I thought I have some conflicts between plugins, but it seems that it’s a normal thing. It’s actually not a big problem. I just have frontend on tab and refresh it to see results. Few tries and all is good :).
