Sterndata:
1. Currently, active theme is Twenty Fifteen.
2. The theme is uploaded from www.remarpro.com but I’ve experienced the same problem when uploading from other resources. Actually, with all other themes I’ve uploaded.
3. Folders: twentyfourteen, twentyfifteen, twentysixteen
Files: index.php

Yes, I’ve tried that. Same result.

Thanks for answer!

I tried the above solutions but unfortunately, the theme will still not display. I could not find error_log or error.log but it means that this does not exist, or what? I have previously used WordPress and never experienced problems like this. What other solutions can, if possible, resolve this problem?
