Hello, after installling a2billing and then connecting to the admin interface I have found that it is possible to edit existing data but not create something new.
For example, if I try to add a Provider and then click "submit data" the resulting PHP page is just blank.
On returning to the interface the data has not been written and saved to the database.
If I edit and existing record like the default trunk entry then the submission is succesful.
Also if I update or add something new to the database directly this is also successful.
Any pointers as to where to look for the cause of the issue would be much appreciated.

Your log files. It's probable that PHP, SQL or Apache is giving some informative message.

Thanks for your response. After much time spent spent trying to locate the issue, I removed and re-installed A2Billing.
Problem solved!
Would have liked to have got to the bottom of it but too much time spent already.
