I'm currently trying to embed a mailchimp sign up form using the HTML widget from impress pages, and at first, it seems to work perfectly fine.
I drag the block onto the screen, a popup comes up, then I paste the form code into it, and then voila! A pretty looking, rendered form appears. I then go ahead and press publish... and bam! My HTML widget is gone, and all that's left is an empty block within the layout asking me to click to add text!
I have no idea what's going on here, does anyone have any ideas? I'm using a custom theme, and I'm wondering if the workaround is to hard-code a widget for my client and just use that (although it looks like it'll be a big drain on my time)
