[Koha] Error 500 in Staff Catalog when clicking at record.

[Caroline Cyr La Rose]

Hi Shafrizan,

Something similar happened at one of my client libraries when they 
updated from 20.05 to 21.05. The problem was invalid 
characters/sequences in the record. In their case, it was in the summary 
field (520$a) and the sequences were something like

(3y (B
(3z(B
’

The record displayed correctly after we edited the records and changed 
those sequences.

I found the answer in one of the log files, though I can't remember 
exactly which one... It said something like "PCDATA invalid char value ...".

The only solution I've found for the moment is to edit the records and 
correct the problematic sequences.

I hope it helps,

Caroline
