Solved - Admin Order Details Page Blank

[salouso]

Hi

I am using PS 1.7.6.7, pHp 7.2.3.4

Suddenly last week when trying to look at the order details on backend (clicking on view on an order in the orders list), I get a blank page with a "1" showing. No errors, debug mode is turned on.

I have tried these steps already without success:
- empty cache manually and from backend
- disabling non-ps-modules and overrides
- deleted the last 3 orders from DB (because before those the problem def. did not happen)

This is still a dev shop, so all orders are test orders only and no one else has access to FTP, backoffice or DB.
Server has not been updated (automatic updates are switched off).
Server logs show this, but not in a timely relation to my attempt on opening an order detail. Delivery Slips I can still download from orders list without a problem btw.

Help much appreciated, as this shop was supposed to go online in a few weeks from now.

Kind Regards

Does anyone have an idea or had this happen before?

Okay, I solved it myself. It was a problem between a payment module and a invoice number module I have installed.
