In one site of mines I enabled both http and https.
The results are:
1) http://ereticopedia-materiali.wikidot.com All is fine
2) https://ereticopedia-materiali.wikidot.com A large part of the theme doesn't work. The SSL certificate is valid but some elements are not secure.
The same problem on the page https://themes.wikidot.com/
Example:
1) http://themes.wikidot.com/preview-st:preview?theme_url=http://themes.wdfiles.com/local--code/midnight-coal
2) https://themes.wikidot.com/preview-st:preview?theme_url=http://themes.wdfiles.com/local--code/midnight-coal
Why this? Is it a general wikidot problem or can I solve this doing some modification to my site?
Thank you all for time and attention.
PS even if I have a free account I can use SSL thanks to the Educational upgrade.
