Writing Bills is not working

Hi everybody,
since December I am unable to create a new bill.
I am using Dolibarr on a Strato Server.
Updated from Version 10 to Version 12 was bringing no solution.
If I change a bill then the same happend, the bill is disapearing. Old bills are visible
Do you have any Ideas?
Thank you
Immo

Hi,

White page means php error => Check your hosting logs.

Hi Ksar,
would you mind to explain how to do this? I have no idea how to do it.
Best regards
Immo

You need to ask your hosting compagny.
Where Dolibarr is installed ?

Hi Immo,

I also use Strato. Try change of company logo to jpg. Let me know if it works for you. If you need further assistance, please contact me info@dolisupport.nl
