    Hi,
    im on wordpress multi-site setup.
    i just noticed, even after deleting a plugin, their data are still available on
    Network Admin > Sites > Settings.
    to be presiced (../wp-admin/network/site-settings.php?id=1)

    for example, i installed a plugin named(elastic email), its an email gateway through API. it didnt worked for me so i deleted it. but later i noticed all its data are available on above link.

    Em Enabled   - 1
Em Username  - my username
Em Apikey    - my api key
Em Url       - elasticmail url
Em Channel

    not only that, i have similar datas of some other plugins which i have deleted as well.
    what scares me that even after deleting, plugins data are there just what i submitted. so i wonder it might conflict with similar plugin which i activate later.

    I recommend asking the plugin’s developers and and their support to help you with this.

    thanks for the reply, but it seems this issue exist with many plugins.
    i didnt installed many plugins in my site but from only those im facing this issue. isnt it quite problematic to contact each individual plugin authors?

    @mrcmanager,

    I understand your concern and frustration.

    All I am saying this is not the right place for this issue.

    The right place is to post at the respective plugin(s) support. That way, you can discuss it directly with the authors of those plugins in question. So that they can take action as appropriate 🙂

    Pluigns do not automatically remove their data from the database unless they are programmed to. If they are or not is 100% up to the authors, not WordPress, so that’s why you need to contact the authors. The more people that let them know that their plugin doesn’t behave as they’d expect it to, the more chance you would have of having them make the changes that are needed to have that happen.

    i understand u guy’s
    and what i did found is, that pluhin which left data on uninstall is not well maintained. so i think you guy’s are right.

    would you please tell me one last thing, where should i look into database to delete those data manually?

    thanks

    The only way of knowig for sure is to read through the source code of the plugin and see where it stores everything.

    Most times, values are stored in the wp_options table, but any other data could be stored as posts, taxonomies, or in custom tables. There’s no way of knowing unless you go though the whole thing and find out how everything is stored and what it’s called.

    That’s a completely different problem that’s not related to this, so you realyl should start another thread about it.

    But… What you’re seeing isn’t a standard part of WordPress, so there is most likely some plugin or your theme that’s got that added to the system.
