prolem in uploading files

Can you post your site URL?

it
https://www.weirdsc.com/site/wordpress

the original url is
https://www.weirdsc.com
the website just loads a blank page , and since i already have a buckup file , i installed wordpress on this directory and i tried to restore the file buck , but i could not

It seems to be a case of site defacement. Scanning tools either cannot scan your site or they report ZERO content. Please contact your web hosting company.
If there is an infection or loopholes left by hackers, there is no fun in restoring the site now without making the site secure.

i did , they said every thing is fine from their side

Does it mean that your site is unaffected or they have provided all possible security measures?

yes , they ment that , i thought first that it has something related the safe mode but now , there is nothing iam sure about.
the imporatant thing is that i have a buckup file but i could not upload it .

Can you login to your cPanel/ File Manager or access your site through FTP and see if your uploads, themes, plugins, WP, etc. are as usual there?

yes , all files are there , but the first problem that i have encountered
is that the screen always shows a blank page although i have not done anything before ( at least 1 week).
then i looked for solutions , nothing worked , so i tried to install wordpress in another directory then use the import tool to get my website buck, unfortunately , it could not be uploaded . this the whole story.

Now, where are the files? Can you post the new location/ URL?

That means nothing is in your site. Is it not? If so what do you expect the site to do?
