When using Chrome, one may encounter this common error. This is most likely that at some point the chrome default settings were changed and thus limiting the functions of extensions in the browser.
To remedy this error so that the Core Extension can function when using the Bridge, please change the following setting back to default.
Right-click on the Core Extension Icon and set the following setting to "On All Sites" as shown below.
Now that it is back on the default setting, attempt to access the Bridge again to make your transaction.
