What is Cached Data? Will it Cause any Problems if We Clear Cached Data?
A number of clients have had problems viewing the most recent versions of web pages OR images on their site immediately AFTER I have made changes. These are all related to your browser storing images / files so that next time, the page loads faster. This is called BROWSER CACHE / MEMORY

Most of the time a simple clearing / refreshing your browser solves the problem by your F5 key, ctrl+F5 keys, OR ctrl+shift+delete, then ‘Clear Data’. Below will show you the steps to do a deeper clearing of your browser cache.

PDFs stay much longer in the memory of your browser. For example, if we make a change to a PDF document and upload it to your site, it may stay on your screen (browser memory) for an entire day. For someone who has NOT seen this PDF prior, they will view it and the correct version will show properly. Even if you do a ctrl+shift+delete, then ‘Clear Data’, the old PDF may still show on your screen.

The BROWSER CACHE / MEMORY is fairly simple, but rather difficult to explain. I hope this is not too wordy!

Like the dust on your bookcase, cached data can quickly build up over time. After deleting your cached data, you may notice pages you normally visit taking a few seconds longer to load.
