I am having this issue too on my portfolio page.
I have no experience in php or other coding so the above recommendation did not help me.
This is what I did try:
If i deactivate the plugin:
The gallery/portfolio section works again but the blog section does not work. It just refreshes the home page of the site.
If I delete the php code from the breadcrumb file:
the gallery works but the blog returns a ‘page not found’ error
If I delete the plugin:
The blog section again refreshes to the homepage and cannot be accessed.
I am not sure what to do as I can’t even delete the plugin without it breaking a very important aspect of the site.
Is there a fix in the works on an upcoming update?
Any help would be great.
Thanks!
