Error after installing OSProperty Plugin

Hello,

After installing plg_cronjobs_osproperty.j2.5.5_j3.x.zip into the OS Property template I get this error on the home page:

Strict Standards: Non-static method OspropertyCron::checklist() should not be called statically, assuming $this from incompatible context in C:\xampp\htdocs\realestate\plugins\system\ospropertyplg\ospropertyplg.php on line 57

Please advise,
Thanks,
Tara

Hi Tara,
No worry, just the php warning, it doesn't effect to cron task process.
Thanks
