Like all good web apps, we often push updates to our servers that then traverse the interwebs and land in your browser. To speed things up, browsers hold on to portions of that code so that things load faster the next time you want it. Unfortunately, that storehouse of data, called a cache, can stick around for longer than it is useful and even can conflict with new versions that try to load later. 90% of all CallPlease errors on the web app are solved by Clearing the Cache!

Every browser and browser version has slightly unique versions of cache clearing and there are level of house cleaning that you can do.

• You can clear your browser history – which is the list of all the websites you have visited. This can be useful if you are starting a new relationship or loading your computer to a child but is not required to keep CallPlease healthy
• You can sweep away all your site cookies and other site data. This will likely require you to recall your passwords to all those sites you login to, but it is a very good idea to do this when you have reset your passwords because of an identity exposure. Not required for fixing issues with CallPlease.
• To make things work with new versions of CallPlease or other web applications it is the Cached images and files that you want to purge. You may be surprised to find out how much memory gets eaten up by this stuff.

Here are some instructions for cache clearing on popular browsers:

• In all instances, close all your browser windows except for one pointed to google.com Keeping a window open holds onto the code.
