I have a form that collects pet owners' addresses for a nonprofit cat shelter. When the cat shelter reviews the form's entries, they have the option to edit the entries and check a box that shows they've recorded the entry in their other system.
I just received a support request today that they're getting an "Invalid CSRF Token" error when they try to save the edited entry.
I also found that a lot of these forms, when reviewed, do not show the selected State in the address field. I can see that a State has been submitted when I look at the database records, though.
I also found that while editing the entry, if I re-select a State for the address field, and then check the "I've Reviewed" box for the cat shelter admins, I don't get the error message when I save the entry. However, when i reopen the entry, the selected State is gone again from the address field. (But still visible in the database).
We just upgraded this install to MachForm version 18.1, although I'm not positive that's relevant. The timing seems suspicious, though.
I've tried clearing my browser's cache & cookies, but that hasn't helped.
We're running this install on PHP v 7.4, if that helps.
