For those interested; The file is called 50-server.cnf and is found in /etc/mysql/mariadb.conf.d/ I added the line as directed above and rebooted, this has resolved the issue in my installation. Thanks
Hi I have just come across this error as well. I did a clean install on a pi4 and restored a freepbx backup from my docker version which I was using for testing. This set the required values for MOH and so I thought it was all fine initially until I went to manually change the url for MOH and then I got this error. Can I manually edit the conf file you mention in your post, will this affect future updates or anything else? Also where do I find this file? Thanks, James
