MrApricot on "[Plugin: RootsPersona] Lots of errors on activation"

Hi there - I have been working on a local WP dev site using DesktopServer for many weeks now and have installed new dev iterations and rootspersona a dozen or more times without issue. Today, however - doing a new WP install in exactly the same way I have been doing, I get a whole slew of error messages on activating the plugin - most of them like this which seem to be the same messages that were occurring due to PHP7 but I am running PHP 5.5.24...this is just the first error - there's a similar one for many of the rp tables

( ! ) Strict standards: Declaration of RP_Address_Mysql_Dao::load() should be compatible with RP_Mysql_DAO::load($table_name, $id_col, $batch_col, $id, $batch_id) in C:xampplitehtdocswww.raisingghosts.devwp-contentpluginsrootspersonaphpdaomysqlclass-RP-Address-Mysql-DAO.php on line 119

I'm guessing it's something environmental but I'm not aware that I'm doing anything different. Any advice would be appreciated.
