SCLogin Popup Not Functioning Well

1. The Login button or text are hidden within the site's black banner and no one can see it in order to lik.

Your template is overriding many of the styles in the SCLogin template file by using the !important tag. You can see in the image below what I'm talking about. This is an image highlighting the styles for the "Log in" button.

At the top of the styles, the /media/sourcecoast/themes/sclogin/default.cssdefault.css file is setting the font color to white, which would show
Further down though, /templates/theme1621/css/template.css is forcing the font color to black with the !important tag

We can't override that, it's something you'd need to do by modifying your template or altering our SCLogin theme file.

2. When I search and locate the text, the pop-up form pops up only for a few micro seconds and then disappears before anyone has a chance of filling it.

I see it disappearing quickly. Can you please enable the "Include jQuery / Bootstrap" setting in JFBConnect. That will include a namespaced version of those libraries which will only work with JFBConnect. That also should prevent other extensions from conflicting with our popup functionality. If that still doesn't work, leave it enabled and let us know so we can investigate further.

3. (Please note that a button never shows either in the Modal Popup or Always Visible state. Is there a way to include own custom button then?).

I'm unsure what you mean here. What button are you talking about?

Thanks,
Alex
