LuxCal 5.2.4 - A "reset to default" bug on the admin's Settings page

A bug on the admin's settings page causes a reset of all check boxes and single-character input fields to their default values each time the Settings page is opened.
The actual settings however, are not reset, unless the settings are saved again after the "reset to default".
This problem can be solved by editing the file "/pages/settings.php" and changing line 57
from . . . .

$pSet[$key] = $set[$key] ?: $value[0];

to . . . .

$pSet[$key] = $set[$key] ?? $value[0];

In other words: by replacing ?: by ??.

This fix will be included in the next LuxCal version
