I have these error and i tried to fix it following the steps in faq:
Open the file /application/config/config.php of your InvoicePlane installation.
Change the value of log_threshold from 0 to 2
But the error persists.
My log: https://paste.ee/r/yjNlZ
Does this error appear after copying a quote or converting a quote to invoice?
If yes please wait until sunday where a fixed version will be released.
Thanks for your answer.
No, the error occurs when I create a new invoice.
Failed to load resource: the server responded with a status of 500 (Internal Server Error)
http://xxxxxxxx/invoices/index.php/invoices/ajax/save Failed to load resource: the server responded with a status of 500 (Internal Server Error)
Does your web server logs any errors? He should based on the given error (500).
These are some weird errors but sadly not related to the error with the invoice creation.
I wait to new version, hope solve my problem.
I install the new version and solve all problems.
