Yes, I was installed the pnn one but found it buggy, but after uninstalling and deleting the pnn one, I installed this official accounting module, but after activation, when navigate to the accounting section it displays 500 server error. so I though its because of prviously installed pnn plugins database, and I empty out the database tables of pnn accounting plugin, but it didn't work for me, then instead of deleting those database tables I just give them an old prefix so it can't conflict with the now installed official accounting plugin, but again it also didn't work and give me the same error of 500 server error.
Do you have any solution or guidance for this issue. Also, I'm using the latest version of UltimatePOS(4.8).
