Hello Rachel-
Thanks for reaching out, we’ll do everything we can to help you get your contact form back.
If you started out building your website with the BoldGrid Inspirations plugin, then your contact form was most likely provided by the weForms plugin. When I take a look at your site, I don’t see any evidence that weForms is currently active.
First, double-check that weForms is still installed and activated in your Plugins > All Plugins list. Hopefully, simply activating it again will restore your form.
If it is already active, there are a couple of other things we can check. First, did the form first disappear when you switched to the Colibri Theme and Builder? Colibri does have its own Forms Component, though it should be compatible with other forms as well.
It also looks like you may be using some kind of performance optimization option, though I can’t tell exactly which one from looking. If that’s the case, try temporarily deactivating it to see if your form works without it.
