ERROR: Could not find the "redcap_config" database table in the MySQL database named "redcap_UB"!

It looks like the REDCap database tables were not created during installation, which means that you may still need to complete the installation. If you did complete the installation, then you may have accidentally created the REDCap database tables in the wrong MySQL database (if so, please check if they exist in the "redcap_UB" database).
