[Koha] 500 internal server error - only in one category

[Scott Owen]

Hi All,

I just upgraded to Koha
Koha version: 22.05.21.000
and imported sql data from a older system  ( 20.05.15.001  )

The catalog looks fine, as well as my "Board" "Staff" and "Teacher"
categories.

However, whenever I select my "Student" category, and try a search in the
left leaving the "search" blank and just searching for the Student Category
,   I get a "Something went wrong loading the table   500 internal Server
error"

Trying to browse by last names gives the same "500 internal Server error"
 error.

If I try typing in a last name, it seems to work, and will bring up a list
of names.

I already tried exporting a 2nd DB dump and importing it clean...same issue.

Any idea where to start ??  It seems like the data is good, it seems like
it's all there. but it's not being sorted / indexed correctly ?
I tried looking in log files, but I really didn't see much .
