I don’t think there is general-template.php in Alora Theme.
But the following code is wrong.
wp_register_style('alora_megamenu', get_bloginfo('template_directory') . '/css/megamenu.css');
It could be redundant code that needs to be removed or it’s referencing the wrong path.
There is no megamenu.css within css folder.
I will report this issue to my employer, Please wait for next theme update.
