Clearing the browser's local database of messages

If your local database of messages became corrupted, you will experience errors when visiting https://client.pushover.net/ and you will be redirected to an error page. You can try to re-initialize the local database of messages to resolve this problem. Note that this will delete all of your past Pushover messages that are stored in your browser.

Chrome

Open the Chrome settings, then click Show Advanced Settings at the bottom. Click the Content Settings button, then click All Cookies and side data. In the search box, type pushover.net, and then hover over the client.pushover.net entry, and click the X on the right side. Click Done, then Done again. Access your dashboard and click Login next to your Chrome desktop device under Your Devices. You should no longer get an error and your database of messages will be re-initialized.

Firefox

Open client.pushover.net in Firefox (it's ok if you get redirected to the error page). Click the Tools menu, then Page Info. Click on the Permissions tab, then scroll down to Maintain Offline Storage. Click Clear Storage, then close the Page Info window. Access your dashboard and click Login next to your Firefox desktop device under Your Devices. You should no longer get an error and your database of messages will be re-initialized.

Safari

Click the Safari menu, then Preferences. Click the Privacy tab, and then the small Details button. Locate the "pushover.net" entry and click on it, and then click the Remove button. Click Done, close the Preferences, and then close and re-open Safari. When you navigate back to the main Pushover website at pushover.net, you will need to login again. Under Your Devices on your dashboard, click Login next to the macOS/Safari device you have registered, and you will be guided through the initialization again.
