We fixed two bugs, I myself introduced with 2.4.14.
With 2.4.14 a user was unable to edit a posting because I forgot to check a few database queries asking for the removed column
email_notification. Same problem was present for the backup function. When the problem was solved I became aware of an additonal problem. When editing a posting, one (author, moderator or administrator) was unable to change the setting for the subscription of the author in the posting/edit form.
You can download the new release 2.4.15 from Github or, if you have already installed a 2.4-release, from the menu page of your forums admin area.
Please report any problems with the new version here.
