I'm trying to check what my form looks like in different browsers. It shows up fine in Chrome but the page is completely blank in both Firefox and MS Edge.
Any idea why?
It is unlikely that different browsers would account for forms not rendering at all (rather than, say, appearing slightly different visually).
I visited your site, but it's not clear where the form in question is. I tried visiting the therapist registration page, which is indeed blank in Firefox, but also in Chrome.
I suspect the reason you see the form in Chrome but not other browsers is because you are logged-in in Chrome but not in the other browsers?
Do you have Access installed? Register user forms are not visible to guests (i.e. logged-out users) unless you go to Toolset > Access Control > Toolset Forms and make the form available to guests.
Perfect - thank you! Having gone down the 'browser is the problem' route in my thinking I didn't even consider this. Thanks for clear and helpful answer.
