After update the child function.php is wrong
-
After the last update, the page no longer works properly. I get white page when I save posts, the pictures in the media library are gone, several other functions are just white.
When I deactivate child, everything will be fine again but not the look I want.
I have tested different methods and circled the error to the code in child function.php which looks like this now:<?php /* * Child theme functions file * */ function colormag_child_enqueue_styles() { $parent_style = 'colormag_style'; //parent theme style handle 'colormag_style' //Enqueue parent and chid theme style.css wp_enqueue_style( $parent_style, get_template_directory_uri() . '/style.css' ); wp_enqueue_style( 'colormag_child_style', get_stylesheet_directory_uri() . '/style.css', array( $parent_style ), wp_get_theme()->get('Version') ); } add_action( 'wp_enqueue_scripts', 'colormag_child_enqueue_styles' ); ?>Also ran WP debug and it also said that there is error in the code above.
How do I fix the error?

Cannot find fault in child. Has renamed all my files in child so that the flow only flows through child without going through any code, yet it is the same error. When I activate Colormag so that it does not use child everything works again Therefore, I think the fault lies in Colormag in the part that connects to child. The error also occurred 2020-09-29, that was when Colormag was updated.Now (2020-10-07) my second blog with ColorMag child stopped working.
The page contains a message from WordPress: “A critical error has occurred on your site.”
2 blogs with the same error a few days in a row ??The error with the other site did not go away when I deleted child. The error continues in the same way after. It looks like the bug is in the ColorMag Theme and came upon latest update but did not show up right away.

Hey!
As of WordPress 5.2, there is a built-in feature that can detect when any extension or theme is causing a serious error on your site and informs you via this email that is sent automatically.In this case, WordPress has detected an error with your theme, ColorMag.
Start by visiting your website (https://www.*****.se/) and check if you notice any visible problems. Then go to the page where the problem occurred (https://www.*****.se/wp-admin/admin-ajax.php) to check if you see anything there.

I’m now doing a restore from a previous back up.I want to get to the bottom of why the child theme does not work. As I described earlier, I get several different strange errors. Among other things, the pictures are not visible in the media library so I can not add pictures to my posts. Several pages in admin also turn white when I click on the functions. I got one of my sites to work with child again. I deleted the child directory and uploaded the ColorMad original directory. Then it worked. My other web page I deleted all files and all code in the child directory except function.php. In that file, I deleted all code except the original code. Continued the same error !!!
Now I’ll find out why it does not work:
I have two test pages. One that I uploaded a brand new child directory I saved from ColorMag online and the other I still have the directory that does not work. I only have function.php and only the original code. This is how it looks:………………………
The code that works in function.php:
/*
* Child theme functions file
*
*/
function colormag_child_enqueue_styles() {$parent_style = ‘colormag_style’; //parent theme style handle ‘colormag_style’
//Enqueue parent and chid theme style.css
wp_enqueue_style( $parent_style, get_template_directory_uri() . ‘/style.css’ );
wp_enqueue_style( ‘colormag_child_style’,
get_stylesheet_directory_uri() . ‘/style.css’,
array( $parent_style ),
wp_get_theme()->get(‘Version’)
);
}
add_action( ‘wp_enqueue_scripts’, ‘colormag_child_enqueue_styles’ );………………………
The code that does not work in function.php:
/*
* Child theme functions file
*
*/
function colormag_child_enqueue_styles() {$parent_style = ‘colormag_style’; //parent theme style handle ‘colormag_style’
//Enqueue parent and chid theme style.css
wp_enqueue_style( $parent_style, get_template_directory_uri() . ‘/style.css’ );
wp_enqueue_style( ‘colormag_child_style’,
get_stylesheet_directory_uri() . ‘/style.css’,
array( $parent_style ),
wp_get_theme()->get(‘Version’)
);
}
add_action( ‘wp_enqueue_scripts’, ‘colormag_child_enqueue_styles’ );
………………………As you can see, the codes are exactly the same and the files they are in have exactly the same name and the two different directories also have exactly the same name but one of them works but not the other?!
I changed codes in the two function.php files, but the function.php that did not work earlier also does not work after I changed codes?!
Now I create a new function.php instead of the function.php that does not work and put the latest code in it and test like this: I create a xxxx.txt file and rename it to fukition.php.
NOW IT WORKS!!!The error is that the function.php is of the wrong format!
Now comes the big questions:
1. How can the file get the wrong format???
2. What are the different file formats on a server?
