Thanks for the quick response.
I didn’t understand the inheritance chain in the WordPress installation and that some configuration had to happen at the network level vs. the website level.
An error I did find–as a side note–on my first attempt at constructing a table I used a CSV file to construct a “bullet” table (fields are either bulleted or not). I attempted this as a simple comma-delimited file, then as a comma and quote delimited file. Both failed. I then tried a unicode & #8226; which also failed. I then tried importing as an xls saved from LibreOffice, which worked just fine.
Thanks again
