I’m using Invoice Plane since the beggining of 2016 and it always worked well, until 3-4 weeks ago. Now, when I try to save anything after having changed a date, an amount, or adding a payment etc… I god an error in the console, saying that :
Failed to load resource: the server responded with a status of 500 (Internal Server Error) The ressource being : http://mydomain.fr/dir/invoices/ajax/save
They weird thing is that I don’t have any memory of having changed anything before the bug appears. I may have upgraded PHP into 7 but I’m not sure if it was exactly at this date (I’m not using the invoice tool every day).
Thanks for helping me !
