A private browser doesn’t save any data file, thus, it’s the best tool to verify a browser’s cache issue. To begin, here are the keyboard shortcuts that you can use to in opening a private window:

• For Google Chrome browser, press keys: Ctrl + Shift + N
• For Mozilla Firefox browser, press keys: Ctrl + Shift + P
• For Safari browse, press keys: Command + Shift + N 

 Once login, try to subscribe to your account. If you’re able to do so, go back to your regular browser and clear its cache. Also, you can use other supported browsers and check if this is a browser-integrated issue.
