For some weird reason, MyBB’s default edit reason for posts is “Improve grammar”, which makes no sense for an Android forum! So I had to change the string for a lot of users. Manually editing the database is unnecessary!
You can exec the following operation in the SQL tab of MySQL:
UPDATE `mybb_posts` SET markedit_reason = replace(markedit_reason, “Improve grammar”, “Unspecified reason”);
So, format is:
UPDATE tablename SET tablefield = replace(tablefield,"findstring","replacestring");[/code][/code]
