I am starting a new thread because you might not have seen the latest reply.
I was able to get in contact with the developer of the plugin.
This was what he said:
"I took a quick look at the error on those pages and it looks like the issue (for this specific error, at least) might actually be in the toolset views plugin, specifically line 2667 of the /wp-views/embedded/inc/wpv-shortcodes.php file. The plugin is using WordPress’ the_title filter, which should pass two arguments – the post title and the post ID – but it looks like the second argument (the post ID) is missing.
Ideally, the views plugin should be updated to pass both of the the_title arguments (the title and the post ID); even if Webcomic were changed to work without the post ID for that particular filter, that would actually break some of Webcomic’s other features (e.g. updating the post title format for restricted comics)."
So it might have something to do with the Views plugin itself.
Please let me know, thanks!
Hello. Thank you for contacting the Toolset support.
Thanks for reporting that and I checked the file which plugin author shared and line number and I see the ID argument is not used with the_title filter.
Please allow me to report this to our Devs and I will get in touch with you as soon as I know more.
