Around the start of this year, Neocities introduced a new stricter Content Security Policy. For those that don't know, a Content Security Policy (CSP) restricts what a page is allowed to load. This can break some widgets on your website.
Free accounts made after the day the new policy was implemented.
So, the old less strict CSP is now a supporter feature. However, if you were on Neocities before it was added, you will keep the old less strict CSP.
Most widgets that do all the following will not work:
fetch()
or <form>
).<script>
tag to embed.Some notable ones are Html Comment Box and Goatcounter.
Everything else will continue to work, such as these:
<iframe>
.<script>
. They usually tend to have the data already in the script itself.Some examples of these can be seen on this website.
