Cache not clearing when importing data

This problem doesn’t always happen, but its very frustrating when it does. Here’s the scenario:

1. We have a table that we use in many different ways on many different pages of our site.
2. The info in the table is maintained outside of tablepress and so we load updates by importing a CSV
3. We flush the WP Engine cache
4. When logged into our site, we see the updated information when browsing our site
5. When not logged into our site (which is the case with all of our readers), the info is sometimes NOT updated. Flushing the WordPress cache again doesn’t help.
6. We can force an update to a particular page by changing the filter even if its in a way that shouldn’t change the results of the filter (e.g. if we had this: [table id=10 show_columns=”23″ filter=”hello” /] we can change it to this to force the new data to display: [table id=10 show_columns=”23″ filter=”hello&&hello” /]
7. The problem with the above “fix” is that we display the same table on many different pages so its hard to go to all possible pages to fix it.
