Blank admin page on updating

[HEPA]

Hi,

almost every time I update a page/post or some options, I get a blank page and have to start from the main admin page. The changes made before clicking the update button are applied.

This issue does not happen with a different template, it only happens with Dante.

What can be the problem?

Thanks

Hi

Have you edited any of the theme files?

– Kyle

Well, yes, although in the Child theme folder.

Following your suggestion I have spotted the file that is causing my problem: it is a custom functions.php inside my child theme folder.

The content is just

<?php
	if (!function_exists('sf_custom_content')) {
			include_once('sf-header.php');
			}	
?>

Since I needed a small modification to sf-header.php

Is there a way to retain my modification while getting rid of the blank page issue?

Thanks

Not sure if this will work but try this:

if (!function_exists('sf_custom_content')) {
function sf_custom_content() {
require_once(SF_INCLUDES_PATH . '/sf-header.php');
}
add_action('after_setup_theme', 'sf_custom_content', 0);
}

Hi Kyle, thanks for your help, but unfortunately it does not work…

[Kyle – SUPPORT]

what part of the sd-header.php did you edit? You will just need to add the function to the child theme, rather than replacing the whole file

More than editing the file, what I had to do was only adding one link.

In line 230 I changed
$header_output .= '<div class="row">. "\n";

to

			$header_output .= '<div class="row"><a href="#" class="bonfire-slideout-button">MENU</a>'. "\n";

Do you know of any other way to do the same modification?

Cheers

You need to copy the whole function into your child theme functions.php file, so:

/* HEADER
	================================================== */ 
	if (!function_exists('sf_header')) {
		function sf_header($header_layout) {
		
			// VARIABLES
			$options = get_option('sf_dante_options');

			$show_wishlist = $options['show_wishlist'];
			$header_left_text = __($options['header_left_text'], 'swiftframework');
			$header_output = $main_menu = '';
					
			if ($header_layout == "header-1") {
			
			$header_output .= '<header id="header" class="clearfix">'. "\n";

But with your change made

Thanks again Kyle. I have made the change, but still with no luck. The problem is still there…

Maybe I have no other option than to modify the main sf-header file, uncheck the automatic theme updates and apply the modification each time I update the theme…

It appears strange to me that I am having this blank page problem only with the backend. The website is ok.

[Kyle – SUPPORT]

Please let me know if it works when you add it to the parent theme file

– Kyle

[HEPA]

Yes, it works.

[Kyle – SUPPORT]

Ok great! 🙂
