I have checked on my server through webmin (which I have installed too in the past to make it a bit easier to do maintenance tasks etc.) and all folder and files are from what i can see owned by www-data which I know I had set in the past to own the www root folder of ninja and its subfolder /files too when i installed Invoice Ninja.
I’m thinking of where that “routes-v7.php file” actually reside in the folder structure of invoice ninja? I been searching for it, but I cannot seem to find it.
I have also downloaded a fresh set of installation files, unzipped it to a local folder and search that for “routes-v7.php”, but nothing found there either…
So I’m a bit puzzled of it (of the location of "routes-v7.php").
