I have created a multipage form that was working fine a month ago, but now under greater use as we are stress-testing it, many people are complaining of experiencing 403 errors when moving forward or back through the form which then deletes their progress and they have to start again.
It is a large for with perhaps 250 fields and lots of conditional logic, but I was assured you could handle upwards of 500, so hopefully it's not a size issue.
Is this a RAM or CPU resources issue? Do we need a larger server to run this? Is there too much on each page or too many pages? Is there a preferred browser to use it? Is the form taking too long to complete that causes this? Is it 2 people filling it it simultaneously?
You can see the form in question here:

Feel free to try fill it in and force an error. We're still in testing phase - we can't go live until this issue is resolved.
Thanks in avance to whoever replies.
