Similar to: Link to parent site is not HTTPS in the sidebar/dropdown "Step 1: Draft your question" on any per-site Meta.
When asking a question on some SE sites, such as Mathematics the sidebar titled "Step 1: Draft your question" (which appears as a dropdown menu on mobile) has the following text:
If your question is about this website, ask it on meta instead.
The hyperlink points to http://meta.math.stackexchange.com/. Note that the link uses HTTP and also uses the old format meta.*.stackexchange.com for the meta site. Preferably, this URL should instead be https://math.meta.stackexchange.com/.
I checked several other sites and whenever the above text appears in the modal "Step 1: Draft your question" (such as Server Fault and English Language & Usage), the hyperlink uses the old format for the respective meta site, and also uses HTTP instead of HTTPS. This text does not appear on all sites: it is omitted on Super User and Unix & Linux, for instance.
Also, note that I am specifically referring to the sidebar titled "Step 1: Draft your question". There is another sidebar titled "Helpful links" which has the text
Ask questions about the site on meta
and — for instance, on Mathematics — the hyperlink on the word "meta" points appropriately to https://math.meta.stackexchange.com/. I haven't checked all the sites in the network, but I believe this aspect is uniform across all the sites.1
Feature request: Please change the hyperlink on the words "ask it on meta" to use HTTPS and to the format https://*.meta.stackexchange.com/ whenever this text appears on the "Step 1: Draft your question" sidebar, when asking a question on any SE site.
1 For the sake of completeness: except for Meta SE (naturally) and Stack Overflow (where it is pushed to the sidebar titled "Have a non-programming question?", which is probably unique to that site).
