Thank you very much for your replies.
We’ve tried and made a new installation of the program in different location, the pdf-function doesn’t work there neither unfortunately.
Below is our conversation with the web hosting company. Would you be able to advise what could be a hint to solve the issue?
Jakub: We use an invoice program on dildizayn.com and the functionality whereby we can generate an invoice into a PDF doesn’t work any more and used to work in the past (for sure it worked until 21 Dec 2020). The issue seems to be on the server as when downloading an the page with this information shows up: 500 - Internal Server Error Please refresh this page or try again later. Would you be able to help on this?
Petar B.: May I know from which page is the program downloading the invoices from?
Jakub: E.g. https://dildizayn.com/invoice/invoices/view/122
Petar B.: This page is asking me for login credentials.
Petar B.: I am seeing quite a few errors in your error log referring to this folder:
Petar B.: 2021-02-16 14:10:42 UTC [apache][core:info] [pid 51496] [client 18.104.22.168:50030] AH00128: File does not exist: /home/u617-olsu6xbsje8e/www/dildizayn.com/public_html/favicon.ico, referer: https://dildizayn.com/invoice/invoices/generate_pdf/123 2021-02-16 13:51:12 UTC [apache][core:info] [pid 35880] [client 22.214.171.124:41186] AH00128: File does not exist: /home/u617-olsu6xbsje8e/www/dildizayn.com/public_html/favicon.ico, referer: https://dildizayn.com/invoice/invoices/generate_pdf/122
Petar B.: After checking, the invoices folder under public_html does not exist.
Petar B.: Is this program set to a specific file path?
Jakub: I’m not sure, would you be able to advise how this can be verified?
Petar B.: Has a developer set this program up for you?
Petar B.: If yes, it would be best if they check if the program is set to a specific file path and make sure that it is pointing correctly to home/customer/www/dildizayn.com/public_html/invoice
Petar B.: However the the folder and files that you are trying to open: https://dildizayn.com/invoice/invoices/view/122 are not present at the moment on the file manager.
Jakub: We set the program ourselves and it worked until few weeks back without problems
Petar B.: I understand. That is why my question was if it is set to a specific file path. Do please try to re-setup the program.
Jakub: Would re-setuping mean losing the current data or will they stay?
Petar B.: I am seeing 2 backup folders for your invoices in the invoice folder under public_Html.
Petar B.: Sadly, I am unable to confirm if the data will stay or it will be lost.
Petar B.: The setup of this program is on the development side and is out of the scope of our support. I have checked on the server in the meantime and it is in full operational status and not what is causing the 500 error. The 500 error is caused by the missing invoices folder.
Jakub: Is it possible to find out where the folder for the invoices should be?
Petar B.: I do think that the folder that you are trying to reach is:
Petar B.: dildizayn.com public_html invoice application modules invoices views
Petar B.: public_html → invoice → application → modules → invoices → views
Petar B.: This is how the application looks to be setup.
Jakub: I set up a new version of the program under “billing”
Jakub: here I set the path to IP_URL=http://dildizayn.com/billing
Jakub: according to the instructions for the program I should be able to access 'setup" by typing www.dildizayn.com/billing/setup in a browser window, but it doesn’t work
Jakub: I also set the .htaccess file to the same path
Jakub: https://dildizayn.com/billing/setup does not work
Petar B.: The billing has to be inside public_html and not outside of it
Petar B.: Because thats where all folders and files related to your website and that are able to be reached by dildizayn.com/ are.
Jakub: ok, I just changed that
Jakub: and when I try again, the message “Your system folder path does not appear to be set correctly. Please open the following file and correct this: index.php” appears
Petar B.: Which file are you trying to reach inside the billing folder ?
Petar B.: This would be the correct link url:https://www.dildizayn.com/billing/index.php
Petar B.: However, it looks like the system path inside the index.php file is not correct. This is quite on the development side of things and sadly it is out of the scope of our support. As much as I would love to help you with this, I will not be able to. We are only able to help with errors related to the server or additional services such as emails. I would suggest getting a developer to look at this.
Jakub: We will ask the software developers. I guess it will be it for now, thank you very much for your help.
