Forms don’t send with plugin activated

Hi,

This is a great plugin! Thanks for making it! Unfortunately it isn’t working correctly for me, when activated it saves the text that is input etc (and I can refresh the page and they stay on there) but when I click ‘submit’ I just get spinning arrows and it never sends the form (in Firefox) but in Chrome and Safari, CF7 Autosaver doesn’t seem to work at all and the form send correctly, like this:

Firefox: Remembers text enter in form, but sending doesn’t complete.
Chrome: Doesn’t remember text entered into a form but sending works
Safari: Doesn’t remember text entered into a form but sending works

Because this is a live website I can’t activate the plugin and show you the page so I’m not sure how to test it…

I would still love some help, please?
