Issue with accessing submission data on the Inbox page

Buenas tardes tengo suscripcion Plata pero nos esta saliendo este error en el Inbox, por favor su ayuda

Hi dgiet.ctea,

Our Spanish Support agents are busy helping other Jotform users right now, so I'll try to help you in English using Google Translate, but you can reply in whichever language you feel comfortable using. Or, if you'd rather have support in Spanish, let us know and we can have them do that. But, it might take a while until they're available again.

Now, coming back to your question, I tried accessing this submission on your Inbox page and was able to replicate the issue.

I have cleared the form cache and this seemed to have resolved the issue.

Give it a try and let us know how it goes.
