If you receive an error message like the following
the reason is likely a bug that affects some users after we release new versions of Code Expert.
Users may end up with an invalid cache in their browser. This invalid cache will cause Code Expert to crash for them.
There are several options to resolve this.
Reset a hidden browser cache (IndexedDB) using the following steps:
Open the developer tools of your browser (instructions for all browsers)
Paste the line of code below into the “Console” tab and press enter to run it:
indexedDB.deleteDatabase('MeteorDynamicImportCache')
An example of how this looks in Firefox. Other browsers look slightly differently, but all have a «Console» tab in their developer tools.
Reload the browser. Code Expert should be working again.
