I saw the same thing. There is a fix.
Not sure how you access the main files for this site, but you are looking for a file called "index.css" . Open it in editing mode.
Scroll down to line 296, you will see the following:
/* Line 296 */
blockquote.bbc_standard_quote, blockquote.bbc_alternate_quote
{
font-size: x-small;
Note that the font-size value is set at x-small. This line should be "commented out."
To do this add the comment tags (/* and */ to the line as shown in red):
/* font-size: x-small; */
Click Save File. That will fix the blockquote font size issue.
