Editing my.ini in ANY way causes mysql to crash

Question

I am making the suggested changes to the "my.ini" file to connect Jira and Confluence. All goes fine except once I make any changes to the INI file. Mysql server won't start until I revert back to the original one. I can't even remove the changes. it has to be the original file.

All running on Windows 2012 server.  Jira, Confluence, and Mysql.

Turns out it was my editor not running with the correct permissions. I got It up and running with the changes. Now Jira won't talk to it but that's another post on this delightful support system.

That suggests your edits are rendering the my.ini file invalid and unreadable.  Not strictly an Atlassian problem, but a lot of us have seen my.ini file errors, so we can try!

Have you tried putting in a simple comment that should not upset it?  Can you tell us what MySQL logs when the service fails to start?

Most suspect for me though is "what editor are you using?".  Some editors may be sticking invalid formatting characters into the file - you won't be able to see them on edit in that editor, but they ruin the content as machine-readable.
