[Koha] Error 500 in Koha OPAC but NOT Staff Catalog After Running Linux System Update

[Charles Kelley]

Hello, all!

    Yesterday, I updated my library's entire catalog. What we did was to
exchange the CCODE and LOC. It worked fine. It took all day and part of
today, but it worked. Then I ran Linux system updates. It too worked fine
-- in staff mode.

    In the patron mode, it's another story. It shows the search screen but
instead of the bib. record with the holdings, we see this response for
every record search:

Sorry, the requested page is not available
> Error 500

> Return to the catalog home page.
> Report issues and broken links
> To report this error, please contact the Koha Administrator. Send email.

    First, what does this mean?

    Second, how do I fix this? If the staff can see the records, ought not
the patrons, also? Since the patrons cannot see the results -- results that
the staff can see, mind you -- why can't the patrons? Did something break
in the last system update? If so, what so?

    Thanks for you help.
