Every month Plek is updated, and sometimes small changes are made in between. After such an update, Plek has to be reloaded to see the changes. This usually happens automatically, but sometimes your web browser still uses the old version of Plek. To force the new version of Plek, you can bypass the so-called cache memory of your web browser. Bypassing the cache means it will reload the site altogether. This has no other harmful effects.
