I installed Joomla 3 on the IIS windows server 2016. My Joomla files located in the inetpub/wwwroot folder.
When I upload an image from Joomla Media Manager, it uploads, but doesn't show.
Then when I go to wwwroot properties/security tab and change IIS_IUSRS permissions checkboxes and apply, It works on the file's permissions and the problem is solved and image shows.
But When I upload a new image, I have the same problem again and the image doesn't show again!
How can I do it? How can I set Joomla or Windows permissions?
I found the solution. I change the permissions on "upload_tmp_dir" (path in php.ini file) folder to match my web app folder permissions. I add IIS_IURS to this folder and set permissions.
