Since a week I cant access files in a WordPress sub-folder through a php curl function. Interestingly it works when accessing the file with a browser. When adding a 'fake' user agent header it works with the php curl function too. But I need other users to be able to retrieve the file without this hack.
I believe a WordPress update made those sub-folders more secure by restricting access to only valid user agents (Browsers). Also I believe that a specific htaccess configuration for this sub-folder will open it up again for all user agents, but I have no idea how to write such a htaccess config.
Does anyone have a clue?
Thanks Aleks
