Wordpress problem / script installer

Hi, so I had multiple problems and still do.

Initially it started that domain wasn’t cached, but I had to use VPN to solve it. After that the scrip installer was down and when I manually installed WordPress, I end up with a problem of login in which didn’t let me go through even if all credentials were correct.

Today script installer is working normally, so I installed WP through it, but next problem that I am facing is to upload the theme.
If i upload it through scriptinstaller view, nothing happens, if I do it in WP, it loads forever.
If I upload it manually to file manager, at end of the upload I get some error of some files Failed upload.

now again trying to open scriptinstaller i get this error
Internal Server Error

500

Error ID 1b54c1b1a9976

cpsrvd Server at sv1.scriptinstall.rocks

So I managed somehow for the installation to go through in WP upload option and without activating it, I am now stuck on website which shows

502 Bad Gateway

We had some issues with Softauculous yesterday, but that should be all resolved by now.

As for the theme upload issues, my best guess is that the theme is too big and that’s causing problems. The Upload & Extract feature of the file manager should let you upload the whole thing without issues.

If that doesn’t work, then the most reliable way to upload a theme is to extract the theme archive on your own computer and upload the extracted folder using a desktop FTP client like FileZilla.

If you’re having an issue with your website now, it would help a lot if you could share what website that is exactly.
