I need to slightly re-state the issue I am having. This is a brand new, "out of the box" install (not an upgrade of a previous version) of both XenForo and PhotoPost Pro 8.0 RC1, and at alternating levels of category depth, the page dispays EITHER breadcrumbs OR category INTROS (not title/description, as I previously stated), but never both. If you try to follow the breadcrumbs up from this category, you will see what I mean. Every one of the categories in this path has category intro set to "Yes" and text in those fields: George Pal & Byron Haskin - Galleries
This issue is not present with PhotoPost Pro 7.1.
I have made no modifications anywhere in either program, aside from the XenForo color scheme, header logo, and custom header.htm and footer.htm files for PhotoPost, and the issue was present before I even did that. I could start hacking the files to try and fix it, but my goal here is not only to resolve my own issue, but to help you track down an apparent bug in RC1 by providing a completely unmodified example.
I have re-downloaded and uploaded the latest files several times, keeping my config files once, but overwriting them and doing a fresh install when that didn't help. Either way, the issue remains. Any help would be much appreciated. Thanks!
