I doubt I would know the platform they are using. Looks like PHP 5 (FluxBB), which should have all the items built in and thoroughly tested. I don’t go near PHP.
Second, it sounds like it literally takes a bit of attention. Given the fact that ongoing issues are still happening, there doesn’t seem to have anybody here.
Yes. Several people have posted code here recently with camel-case tags and not corrected them.
The only way I’ve been able to reproduce an automatic switch to camel case on my Mojave system is to have “Correct Spelling Automatically” checked in the “Spelling and Grammar” sub-menu of Safari’s “Edit” menu and (presumably) to have the word “AppleScript” in a spelling dictionary somewhere.
“Spelling and Grammar” is normally greyed out in my Safari unless the page being displayed is one in which I can enter text, such as a MacScripter posting page, so it can only be checked or unchecked while such a page is showing. The setting sticks, so there’s no need to keep doing it unless you actually want to change it.
