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 On 2022-06-07 08:12, Shafrizan Affendi wrote:
Hello all.
5 days ago I upgraded my Koha from version 19.* to 21.11.05. During the upgrade there is no error message that I notice. Then I upgraded my OS from Debian 9 stretch to 11 bullseye. Same no error message.
When I searched in staff opac the result came out fine. For example i search for "management" and the list related to management shows up.
The problem started when a certain record from the result gave me An Error Has Occurred! Error 500. When I hit the back button and click 'Edit Record' or 'Edit Item' it worked fine.
I tried to look at the record detail when I clicked Edit Record or Edit Item but I found nothing unusual. I compare with no problem records. Not all records gave me this error but I noticed some of it.
I already tried running /usr/share/koha/bin/maintenance/touch_all_biblios.pl -v but the result came out with no error at all. I do have full access to the server and database if anyone can help me and need extra information.
FYI Opac worked just fine if i clicked on the record. Only at staff Opac.
If anyone here can help please reply or maybe can lead me to where i can investigate to solve this problem.
Thank you very much... _______________________________________________
