You can use a Plugin to switch off the cache site wide:
1. Create a new plugin, name it
DisableCache or whatever you want.
2. Enter the code:
$modx->documentObject[’cacheable’] = 0;
3. On the System Events tab, check the
OnLoadWebDocument
4. Save it.
5. Refresh the site.
It will disable the cache all over the site no matter document caching is enabled in each document or not, this will save your time changing each documents caching settings and when you switch your host which I personally suggest

, you wont have to re-enable the caching on every document, instead just disable the plugin.
Hope it helps
regards.
