Hi Omar,
Thanks for the further response via email. Please see my answers below:
1. The side arrow issue has been fixed in the latest beta version, you can delete the current beta and download the new version to test if you wish.
2. I can see the header image for the children page there as on all other pages, are you still not seeing the image?
Please let me know if all is as it should be now and many thanks for using the plug-in!
Many thanks
Peter
