Hello I have next problem after I import my laravel app from WIN 10 to Debian 8.3. In my app when some create ofert in db he can upload scan file to server. Path to store folder is 'myProcject/public/storage/doc/$year/$month', simple. After I install app on debian evrything is work until someone wants to upload file to server. I got error mkdir(): Permission denied. I have tried change privilages to all folder to 777 and etc. but nothing work still got this error. Has anyone already encountered such a problem?
