Logo disappeared from header after X update

Hi there
The logo has disappeared from my site after updating to X 5.2.1
I’ve added the image (jpeg) in again several times - it shows in the preview but after saving changes and viewing in the front end it disappears (text logo is shown instead).
Please could you help
Best wishes
Sarah

Hey Sarah,

Thanks for writing in! Please be advised that we have release X 5.2.2 and Cornerstone 2.1.2. It is now available in automatic updates. You can now update to this latest version. This latest release contains fixes for several issues so be sure to check out the changelog (http://theme.co/changelog/).

After doing the updates, always remember to clear all caches (if you are using WP Rocket, WP SuperCache or W3 Total Cache) when updating so that the code from the latest release is always in use. This will help you to avoid any potential errors.

Hope this helps. Please let us know how it goes.
