Thanks Katya, it's definitely something to do with the SendGrid service. If I don't touch the service the website works fine.
Something weird is going on. Maybe it's a problem with the SendGrid service because now when I test the app, on clicking the 'Submit' button, which should invoke the SendGrid service, is no longer working.
Just re-logged in another browser. Seems to freeze when I go to the Data tab and click 'Edit Mapping' for the SendGrid service. Or if I click 'Save' nothing happens :S
Thanks Katya, you've been my saviour this week!
Unfortunately I can't test it at the moment as the Appery website seems unresponsive this morning. Do you know if there is a problem?
Still struggling Anyone? Thank you.
Ok thanks Katya, I'll give that a try. I'm still awaiting my SendGrid account to be provisioned so unfortunately it's hard to test it.
