Unfortunately, the shortcode from the theme part of download bundle does not contain this option at present. I have updated the shortcode to have this option and will post it here as an attachment in a private post. Pls load the same into framework/shortcodes/ directory (replace the existing file) and you can then use the attribute department for the shortcode. Pls use the department slug for query (more than one department, separate by a comma).
I don’t think this has anything to do with the shortcode. The change has been well tested by me and the error looks to be a generic one, not related to the change made. Have you retried or reloaded the web pages to see if the error goes away? Is it repeatable? Pls let me know. Thanks
Can you post a temp FTP login for your site so that I can make this change and see what’s happening? There is nothing really big here that should cause this issue. I can make the change from the wordpress login but editing PHP files from WordPress can make the site go down with a slightest mistake and hence need the FTP before I can make these changes. Thanks!
