You can hide an RSS feed by changing the value of web.enabled
parameter to false in the [customSpots] section of the
panel.ini
file.
For example, the description of an RSS feed that is not shown in Plesk
may look like the following:
[customSpots]
web.enabled = false
web.type = rss
web.params.url = "http://kb.plesk.com/rss/gen.xml?&ArticleLanguage=en&Type=LastCreated&Product=8&UpdatePeriod=daily&ArticleType=all"
web.params.count = 3
