Dear Modern Tribe and other readers,
As a WordPress developer I always change my table prefixes.
I don’t use wp_ but instead use something like wprandom_, to ensure a little bit of extra safety from injections etc.
In the case of this plugin however the database prefix is hardcoded in the queries on multiple places. So untill this is fixed; everyone else that experiences this: Change the queries in the plugin (but mind your updates!).
Modern Tribe: please don’t hardcode the prefix in future updates?
