Wordpress RSS feed vimeo called in a metabox - bug XML error

Hello, I have a problem on my wordpress website when I try to call RSS vimeo albums to create video portfolio with the CMB metabox WP plugin and justified image grid plugin.

Everything worked fine until this week and I don’t know why…

Now on my page, I have this sentence : 

The requested RSS feed cannot be loaded at this time. This XML document is invalid, likely due to invalid characters. XML error: XML_ERR_NAME_REQUIRED at line 1, column 2

Instead showing the album with the videos.

The abum is call by this code in a file called single-directors.php : 
<div class=‘vimeo-rss-container’>
<?php echo do_shortcode(’[justified_image_grid preset=17 caption_field=off row_height=300 height_deviation=70 prettyphoto_theme=dark_rounded lightbox=magnific lightbox_max_size=full last_row=match disable_cropping=yes link_target=video rss_url=’ . get_post_meta($post->ID, ‘_director-vimeo’, true) . ‘/rss rss_links_to=permalink rss_description=description rss_link=yes rss_link_text=“Watch on Vimeo”]’); ?>

I think there is a problem with the syntax but don’t know exactly where.
I’m looking for an issue since 2 days but didn’t find anything which works… Anybody here should have an idea ?
Thanks a lot for your help, I really appreciate !

Could you post the actual XML document that contains the error here?


Here is the bug (visible with the sentence, middle of the page instead to have the protfolio…) https://karusfilms.fr/directors/cecile-rogue/

Thanks a lot,

This is a returning error, solved by some interesting investigation :slight_smile:
Actual XML was in fact a HTML page, because the server got served something else than expected.
I’m the author of the plugin referenced above. Closable.
