ok, i've tried what you suggested but on response.meta.keywords:
list(response.meta.keywords).append(', '+c.keywords if c.keywords
else "")
which does not except out, but when i view the final html code in the
browser, web2py still returns:
<meta name="keywords" content="<map object at 0x7f42e140f9d0>">
on the new centos 8.2 server. BUT on the old centos 7.6 it returns the
proper string of keywords.
