I am deploying a Moodle-based project on a server under Linux. Now it is still local, bit I am getting it ready to be placed in the Internet. At first the site was deployed locally on Windows 2019, now its copy is placed to another server, under Linux.
The problem is, that the background image of login and registration pages is displayed in the version under Windows, but is not - under Linux, as it ts shown below.
Windows:
Linux:
Of course, maybe, the reason is not in OS, but in some settings. The PHP version is practically the same (7.4.29 - 7.4.32), all the PHP extensions, demanded by Moodle itself, are installed. What's wrong? Is this "the fault" of Linux, or ane additional PHP extension is needed, or what? Help th understand, please.
Adaptable v 4.0.1.2, Moodle v 4.0.4.
