Hello Bernard,
Thank you for reaching out, and we sincerely apologize for the inconvenience.
I have checked both issues, and I can confirm that there is an issue with the Social Media Share buttons disappearing when the Author Posts option is disabled. I have already informed our template team about this, and they are working on a permanent fix.
As a temporary solution, please replace the following file:
JRoot/templates/newsberg/html/com_content/article/default.php
with the updated file provided in the hidden content area.
Regarding the Article Blog Featured Image upload issue on your live server, could you please provide us with Super User access to your Joomla website? This will allow us to investigate the issue directly and identify the root cause.
We appreciate your patience and look forward to resolving this for you.
Kind regards
