In our opinion is this plugin missing some important code, namely; it does not clean any data from your database after deleting(de-install).
-All questions which are created during the use of this plugin are not deleted after de-instalation. (FYI: a question is a custom post and is stored in the wp_post table and will NOT be deleted.)
-All answers which are given on those questions are NOT deleted after de-instalation. (FYI: an answer is stored in the wp_post and wp_options table and will NOT be deleted.)
-All comments which are given on the questions/answers are not deleted after de-instalation. (FYI: comments are stored in the wp_comments table and will NOT be deleted.)
-Pages which are created by this plugin will not be deleted after de-install.
Not deleting the comments means also it can cause a php Notice, for ppl which have debug active. This notice will stay till you remove all comments which belong to the questions, WOW that will be fun when you have/had an active community and you decided for whatever reason not to use this plugin anymore. (of course you will have the same problem even when you just where trying out this plugin and have it de-installed for whatever reason)
People which have debug activated:
Be aware your logfile will be -drastically- filled up after de-installing this plugin, have fun!
Depending on configuration, your back-end will have this also visible. Click home and have fun when you see the Activities Colomn. Pray you have/had not to many comments on the questions. Same for the Comments page in the back-end.
Maybe all is only happening because the way we have our configuration/site which is created for a huge community, who knows, but omg are we glad we found out a) during our development b) at first stage of testing.
Hint to development of this plugin, FIX IT.
I think many other plugins still keep database even you de-active a plugin or reinstall them. You should consider remove them manually.
Thanks for your suggestion. We will consider adding this feature to DW Question & Answer later.
PS: I was tried to deactivate this plugin, but I didn’t see this message. Can you give me a screenshot and tell us your PHP version for further checking?
