I did this. Saw that there is shown, that it is disabled file_get_contents. As in different support tickets, was written that it should be asked to hosting company, already asked them. And this was their response. But I have already installed safe swg plugin.

Hello,
There is no server-side ban on SVG uploads for WordPress pages. All file formats are allowed to be uploaded from the server.
By default, WordPress does not allow you to upload SVG files.
This is done for security purposes.
You have the option to install separate plugins for your WordPress page that allow uploading files in SVG format.
