To fix this simply deactiave and activate AnsPress. This bug has been reported already in our support site and already fixed in 3.0.0-alpha1 (You have to wait for stable release). * Thread Starter [nabtron](https://wordpress.org/support/users/nabtron/) * (@nabtron) * [10 years, 1 month ago](https://wordpress.org/support/topic/database-error-doesnt-exist-for-query-select/#post-7301484) * no i didn’t update ur plugin manually, ever. * anyway, solved it already by deactivating and reactivating. * Thanks. * Also, i would like to contribute to your plugin as it has many bugs, how is this possible? I don’t want to fork it and create a new plugin out of it as such. * Plugin Author [Rahul Aryan](https://wordpress.org/support/users/nerdaryan/) * (@nerdaryan) * [10 years, 1 month ago](https://wordpress.org/support/topic/database-error-doesnt-exist-for-query-select/#post-7301487) * You are most welcome.
