Tell us what you are trying to do?
Insert a toolset-edit-post-link shortcode to replace existing cred-link-form.
This code was originally in my content template:
[cred_link_form form='79165' text=" +"]
As a test, I have also added the following, using the Toolset button in the editor to do so:
[toolset-edit-post-link content_template_slug='advert-edit-page' target='self'] ++[/toolset-edit-post-link]
I am pleased that cred_link_form still works (built c. 2015!), but assume it's deprecated...?
When clicking on either of the links, they display the output in the default content template for the post type - expected for the first, but not for the second. What could be causing the second to use the default content template rather than the 'advert-edit-page' content template?
The post you link to doesn't provide much detail on which plugin was causing the issue so in this case you will need to temporarily disable all your non-toolset plugins and check again to see if the issue still remains.
So I would suggest going through the plugins one at a time when reactivating to see which one causes the issue.
