Ensuring the latest information

When using PICMI (like any website or application), you might encounter issues that seem confusing—like seeing outdated information or changes not reflecting right away. This could be due to a cache problem.

Understanding cache problems

A cache is like a storage space where frequently used data is saved to make things load faster. For example, your browser or an app might save images, settings, or other data so it doesn’t have to load them every time. However, sometimes the cache doesn’t update properly, causing you to see old content or preventing new changes from showing up.

To fix this, clearing the cache is often the best solution. This removes the saved data, allowing PICMI to load fresh content and resolve any display or performance issues. We should only do this temporarily.

Normal and hard refresh

1. Locate a Refresh on the page
2. Press (click) and HOLD, waiting for a menu to appear
3. Select
   • Normal Refresh
   • Hard Refresh (disable cache on all requests that are part of the refresh sequence)

note

If this still does not look right, continue with update old information below

Update old information

1. At the top-right of PICMI, click User Menu
2. Select Update old information
3. Update the Reset in seconds (if longer is needed)
4. Click FORCE UPDATE when you are ready
5. Continue using PICMI

note

PICMI will revert to its default behaviour after the reset in seconds time

Disable cache in browser

This technique only works for as long as your Developer Tools are open. Once you close the Developer Tools, the browser will revert to its default caching behaviour.

Here’s how to disable the cache in Developer Tools:

Chrome, Edge, and Firefox

1. Open Developer Tools:
   • Press F12 or Ctrl + Shift + I (Windows/Linux) or Cmd + Option + I (Mac) to open Developer Tools
2. Once Developer Tools is open, click on the Network tab
3. Check the Disable Cache box near the top of the Network tab to turn off caching
4. Keep the Developer Tool pane open
5. Reload the page using the browser button at the top-left and continue using PICMI
6. Close Developer Tools to restore normal cache behaviour
