I downloaded the theme files and uploaded to Wordpress.

Then I did the Salient plugins installation

All plugins installed successfully, except for salient-core plugin

When I tap install on salient-core plugin, This writing appears:

Downloading installation package from /home/..../htdocs/wp-content/themes/salient/plugins/salient-core.zip…

Download failed. A valid URL was not provided.

When I go to the file manager for the site, I find that the plugin does not exist, and all I try to upload the file (salient-core.zip) the plugin disappears.

I hope you can help me soon

Best Regards,
