Hi,
I'm relatively new to SharePoint and Infopath, but I have a form that was created about 7 months ago that has been submitting fine up until this morning. The form is submitted to it's own library within SharePoint. I haven't made any updates to either the form or the SharePoint site in at least a couple of weeks. When users try to submit the form, they get an error that says:
Warning
The form cannot be submitted because of an error.
Click OK to resume filling out the form. You may want to check your form data for errors.
An error occurred while using the form. For more information, contact the site administrator.
An entry has been added to the windows event log of the server.
Log ID: 5567
I've validated that the data connections within the form are all valid (meaning they point to valid lists and libraries) and when I've tried filling out the form myself, I've made sure all of the required fields are populated with valid data. As I mentioned, I haven't touched the back-end of the form in a couple of weeks (during which new forms have been submitted successfully) and there have been no changes to the SharePoint site, library, or lists.
I have other Infopath forms that are submitting just fine to other SharePoint libraries, so it's just this one form/library.
Any help anyone can provide would be greatly appreciated!
