HI,

I have forgotten how to do this. I have created Types called Training Courses, so within this I want to create courses and then apply them to 3 different sections which will be on different pages. First Aid training, Life Support Training and Mandatory training.

Please share a link so I can do this, thanks

I think I would create Taxonomies, you can correct me if I am wrong, but something else please see this error.

Thanks, that issue is resolved, any advice about my initial query?

I created Taxonomies, but they are not showing within the Types section.

Can you please share few screenshots of your issue? - where exactly you want to display the taxonomies?

#1262259

I am happy to share access, what I am trying to do is create numerous listings, however, they can appear in different categories.

See screenshot, 1 is a First Aid Training Course and 2 is a Life Support Training Course, so I would like to have the ability to have them applied to different categories.

I will then on the front end have these 3 categories First Aid training, Life Support Training and Mandatory training and on each page, the courses relevant will show.

Yes but I see you do not connect your taxonomy to post type.

*** Please make a FULL BACKUP of your database and website.***
I would also eventually need to request temporary access (WP-Admin and FTP) to your site. Preferably to a test site where the problem has been replicated if possible in order to be of better help and check if some configurations might need to be changed.

I have set the next reply to private which means only you and I have access to it.

Well - I've created another taxonomy and I can see its available with the post type "Training Courses"

I think there is some issue with the taxonomies you created, I suggest remove the current taxonomies and try to add brand new taxonomy with smaller slugs and that will help you to resolve your issue.

I think the issue was related to the server change that needed to be done, as I created those categories before I added that php update. Thank You
