Publishing Error on Every Product

[Primeaux]

For every product in the editor, the publishing box initially loads as usual, showing "approved for 9 markets" (my typical message), but after about a minute, it changes to a red error message in the Publishing box that says 'An Error Occurred While Loading Publishing Data.' This issue is occurring across all products. However, this has not affected sales on my website as a purchase was made. Is this happening to anyone else?
