unable to create output file for invoice

Hi!
I have added the invoice feature to membership pro and when i test it to see how everything looks i get this message:
TCPDF ERROR: Unable to create output file: /home/adminudesign/public_html/tradingcoacholi.com/media/com_osmembership/invoices/2017/00000053.pdf. On the backend i see there is a pending subscription but i dont receive the email either that i have subscribed.
Before adding this feature it all seamed ok...
Please advice me on how to fix this.

Also is it possible to add the prefix (or something like this) after the invoice number so instead of 2017/001 i can have 001/2017?

Thanks in advance

Same problem. Some solution?

Hi Daniel

As replied via support ticket, it could be permission issue of the folder which invoice is stored or the hosting account is full

Please reply via support ticket sending us super admin account of your site. I will check to see why the issue happens and get it sorted
