PHP Fatal error: Call to undefined function php_uname()
-
After updating PHP to 8.0, we are getting the following error when making backups. Our host refuses to enable php_uname() as they state it is a security risk. Can you help?

Ah ok, I see.
Since this is an issue while compressing the database backup file, as a temporary workaround you could disable the database backup file compression.
To do so, in the iTSec plugin menu navigate to:
Security > Settings > CONFIGURE => Utilities
And untick the Compress Backup Files checkbox. Then click on the Save button at the bottom of the page (You’ll probably need to scroll down to see the Save button).
It’s probably best to monitor/evaluate database backup (uncompressed) file size, available disk space, backup method and number of backups to retain in order to determin whether this is a viable option.
Would it be possible for the Database Backups feature to use ZipArchive by default and pclzip as a fallback for file compression ? (Similar to the WordPress core unzip_file() function). It would make file compression of the Database Backups module more robust.
Any idea why WordPress core does not have a zip_file() function ?
(Looks like WordPress doesn’t include any functionality that needs zipping).
