You're trying to select an element, but nothing happens. There are several symptoms of this behavior:
If you see an error that says “Cross domain recording is not possible due to security issues..”, this likely means that your account has not been set up for Cross Domain capturing. Please reach out to your AM/DAC and request your account to be set up for Cross Domain capturing.
This can sometimes happen with sites that are Single Page Applications. Use the “Auto Detect” feature on the Single Page tab in the Editor to confirm that the correct SPA settings are configured.
If the SPA settings are already correct, try refreshing the page and the Editor, or restarting the Editor
You should also determine whether it's an issue with the site itself, or the Editor. Try building on another site with the affected Editor (such as Wikipedia) to rule out it being an issue with Editor.
If none of these instructions allow you to capture a specific element, please contact Support for further investigation.
