Our website here:
https://rchsdigitalcollections.epistrophypictures.com
...has been up for almost two months now and things have been going pretty well. There are some header/pages I added that were temporary that I want to update to the preferred method soon, but before that I decided it was time to add some collections.

I have a local test site on my computer and adding collections there works fine. Adding collections to the live web version is not working. Currently the page is not accessed traditionally via the Browse header, but by a new header called: Street View Archives. I don't think this caused the problem, but I could be wrong.

To try to trace the problem, I added "get included files" code to the site index page on both versions of the website. I am listing part of the readout from both versions of the website:

Online version:

...end of readout

Local test version:

/opt/homebrew/var/www/ca/pawtucket/app/models/ca_bundle_displays.php
...etcetera...

In the online version, after the html purifier lines, it skips to Collection search result. But in the test version that works correctly, the next line goes to Ajax Footer. Not being a coder, I have not been able to determine why the process for the online version is getting abbreviated.

Any clues how to fix this very much appreciated, thanks!
