Good day. I am using Koha version 21.05 and 21.11 on local and offsite servers respectively. When I try to enable the Advanced Editor for the catalog, I get a 500 error which also affects the standard editor when it's enabled. Any help would be appreciated. Thank you. P.S- no updates were done on the system. Do I need to change something on the server? We run Apache on ubuntu. Thanks again.
Hi, there was a bug fixing a similar issue. Please check your exact version to see if the fix is already included in your installation or not: Bug 33375 - Advanced editor crashes when using MySQL 8 due to reserved rank keyword See: Version(s) released in at the top section of the bug
Hm, I realize if it's this bug, it will be neither fixed in 21.05 nor 21.11. Can you confirm if you are using MySQL8?
