I have this problem too. When I am on the Money > Invoices page, the invoices do not display; all I see is “Loading…” underneath the column headings.
Seems that multiple questions have been asked in the Forum regarding this issue but I cannot find a definitive solution to this problem.
“Due” is the only filter that works to actually display invoices (only the due invoices). The ‘All’, ‘Paid’, ‘Real’ filters don’t display their respective invoices.
