Every month Plek gets an update and sometimes small changes are made in between. Sometimes your web browser will still use (parts of) the old version of Plek after these changes. To force the new version of Plek you can bypass the cache memory of the web browser. Bypassing the cache will reload the site from scratch. There are no further negative effects in this process.
