Preview of Revisions not Working for Some Users

I’m also experiencing this issue. Any help would be greatly appreciated.

I was possibly able to fix this temporarily. In the front_rvy.php file, lines 125-130, I replaced:

if ( $id ) {
if ( ! $template = rvy_get_post_meta($id, '_wp_page_template', true) ) {
if ( $revision = get_post( $id ) ) {
$template = rvy_get_post_meta($revision->post_parent, '_wp_page_template', true);
}
}

With:

if ( $id ) {
if ( ! $template = get_post_meta($id, '_wp_page_template', true) ) {
if ( $revision = get_post( $id ) ) {
$template = get_post_meta($revision->post_parent, '_wp_page_template', true);
}
}

Not meaning to bump this, so I apologize in advance if I am, but this seems like it might be related.

I am having the same problem as ISSUE 2, except (here’s where I am not meaning to add confusion), it is happening for a certain page (2 pages actually) not a certain user, and it is happening in Scheduled Revisions and Pending Revisions. Also, I get a Page Not Found message not the error you are seeing.

Notice the URL is different too:
Preview works: https://mywebsite/page/?preview=true
Preview doesn’t work: https://mywebsite/page/&post_type=revision&preview=1&post_type=revision?preview=1 (if I replace the end with the working URL, still get 404 error)

I tried the above edit and it didn’t work. Again, I can start my own thread, but I thought this might be related. Thanks!

Andrew’s fix was a major help! Nobody on my site was able to preview the pending posts, but that completely resolved our issue! Thank you!!

Hi,

Can you advise please if
1/ Revisoinay works with WP 3.9.2?
2/ Doe it work also with s2members ?

Thanks
Peter

Here’s a fix for this issue that does not involve modifying the plugin. Add the following to functions.php in your theme or child theme:

if (! function_exists( 'rvy_get_post_meta' ) ):
function rvy_get_post_meta( $post_id, $key = '', $single = false ) {
    return get_post_meta( $post_id, $key, $single );
}
endif;

Thanks @zbyte for the simple fix. Seems to work in WP4.0

Thanks @zbyte! It worked for me as well.
