problem with uploading files on my hosting server

[mindanda]

I bought a Rival Premium theme and I have tried many times to upload it on my hosting server but the website does not appear. The index page is just white.
Could someone help me.

Hello,

Please enable debug and post your debug.log so we can see the errors. https://doc.osclass.org/Debug_PHP_errors
You can also ask the theme developer on Osclass Market.

Regards.
