I have an Apache web server that has a sub folder for images. For some reason, a few of the .png files are returned as text/html and not as image/png.
There is nothing indicating a permission problem and the files return with code 200 and with full size. I made sure that image/png is set and even tried forcing it with .htaccess
Any idea where to look next?
Edit: looks like an .htaccess configuration problem on a parent directory.
