thumbnail without login

Resolved szekitom

I added the function.php this line:
add_filter("um_restrict_post_thumbnail","__return_true");

It still worked in the summer, but since then something has changed and it no longer shows tumbnail pictures.

What can I do to make sure that people who aren’t logged in can see the posts thumbails?

Hello @szekitom

This filter hook is still available in UM core. So, it should work fine. Have you checked if there are any other issues? Can you please mention which version of UM are you using?

Hi,

Yes I see in the source code, but I’m not programmer, not understood when what happen. UM has also been updated since then, as have the other components (PHP, WP) Now everything is uptodate:
– UM 2.5.1
– PHP 8.0
– WP 6.1
My theme (8Rise) don’t show error message

<div class="blocksquare" style="background-image:url(<?php if ( has_post_thumbnail() ) {the_post_thumbnail_url('thumbnail512');} ?>);">

but another (Mantra) theme put an error message:
Warning: Trying to access arra offset on value of type bool in
…/mantra/includes/theme-loop.php on line 249
This is theme thumbnail code:
```
function cryout_echo_first_image( $postID ) {
	$args = array(
		'numberposts' => 1,
		'order'=> 'ASC',
		'post_mime_type' => 'image',
		'post_parent' => $postID,
		'post_status' => 'any',
		'post_type' => 'any',
	);

	$attachments = get_children( $args );

	if ($attachments) {
		foreach($attachments as $attachment) {
			$image_attributes = wp_get_attachment_image_src( $attachment->ID, 'custom' )  ? wp_get_attachment_image_src( $attachment->ID, 'custom' ) : wp_get_attachment_image_src( $attachment->ID, 'custom' );

			return esc_url( $image_attributes[0] ); //this is the line 249

		}
	}
}
```
For some reason don’t get the image.

The filter looks like registered fine.

global $wp_filter;
$hook = ‘um_restrict_post_thumbnail’;
print_r( $wp_filter[$hook] );

The output is here

Hi,

I found a trick or a bug.
If only the post is restricted, the thumbnail will appear on the main page.

If the category of the post is also limited, the thumbnail will not appear on the main page.

The picture has same category of the post.

I think the “filter_post_thumbnail” function doesn’t check the “category” and doesn’t allow the thumbnail image. Or I don’t know where the error is, but this could be the solution

I hope the description of my problem is understandable!

Best regards,
Tamás

Hello @szekitom

Sorry for the late answer. Have you solved this problem?
Please let me know if you need our help.

I checked the “um_restrict_post_thumbnail” filter with post and category restriction and this hook works well.

Thank you.
