Executable .pdf File

The code snippet, it is right I think as I can see here https://stackoverflow.com/questions/13396033/blocking-pdf-files-from-direct-access-using-htaccess

Maybe there is a setting in the Apache server that doesn’t allow restricting access to PDFs with this code…

But as you can see, this snippet works fine for php files.

THE ONLY THINK THAT I CAN CONSIDER NOW IS TO
1) buy Library Viewer Pro: https://www.pexlechris.dev/library-viewer/pro/
2) create a folder with random name here and in it to place the “library” folder https://mblcosmetics.gr/randomname/library/
3) use the shortcode [library-viewer path=”randomname/library” have_file_access=”logged_in”]
4) and place the file in “library” folder here: https://mblcosmetics.gr/randomname/library/tests.pdf

This that user will see in the frontend will be same as this that see now, but he/she will not know the real path of the file…

Thank you. I have purchased the pro version and all its fine!
