Hi,
I know this is an old thread,but I am encountering this same problem with my web-enabled form. My form has no code. My problem is it started to intermittently show up this error on publish. And now it just would not publish. I thought it could be linked to our sharepoint servers running on low RAM but that has now been fixed, and my problem still exists.
The Design Checker does not help either as it also just tells me it could not verify the form. The form publishes but clicking the "Add new item" on IE opens up InfoPath, and on Chrome/Firefox, it comes up with a Correlation ID error.
I've already tried to look into into the different XML files that make up the .XSN (eg, manifest.xsf). I originally copied this form from another similar, as I did not want to redo some logic from the other form which I also need on this new form. And I have diligently remove rules and fields I do not need. I can see in the Rule Inspector and even in the manifest.xsf that all appears good. (Except the Rule Inspector does not seem to like double evals for some reason--but I kept it since they work on the original form that I copied from).
Could anyone help. I've been working on this form for weeks trying to fix it and I'm at the end of my wits.
Thanks in advance.
