Hello,

To make the debug easier, please install the plugin called “Code Snippets” and drop this code into it:

update_option( 'mwl_obmode', true );
update_option( 'mwl_parsing_engine', 'HtmlDomParser' );
update_option( 'mwl_rendering_mode', 'rewrite' );

It only needs to be run once, and it set the settings used by the Meow Lightbox. Those options above are quite safe, and they are not the default ones currently. To get back to the defaults, please use this.

update_option( 'mwl_obmode', false );
update_option( 'mwl_parsing_engine', 'DiDom' );
update_option( 'mwl_rendering_mode', 'rewrite' );

Basically, it’s better to avoid the OB mode. Without it, however, the Meow Lightbox will only analyze the content of the page/post (not the whole page). DiDom and HtmlDomParser are DOM parsers. DiDom is faster, but if your HTML is somehow badly formatted (it happens, it can be anything even though it looks fine), it might break it even more (actually by making it technically correct). In that case, HtmlDomParser is a safer solution.

The mwl_rendering_mode can be set to ‘replace’ as well, you can try it too. If you use the OB mode, the rendering mode will be forced to ‘rewrite’.

Please let me know here which solution works for you.
