I’m not sure what you’re asking here.
RW 6.0.6 is very old (January 2015). It’s not even the most up to date version of RW6 (6.4, May 2016).
The current release RW8.9.3 (November 2021) is two full releases above what you are using, so there’s quite a bit that has changed.
It looks like you are using the split theme. If I remember that came with RW7, so I’m guessing that you purchased the theme from the developer? If not then I’m not sure where it came from.
My memory might be wrong here, perhaps split came with RW6. The split theme that’s included with RW8s current version has had the jQuery fixed. That’s where I got the line of code above.
As for the Google font, that’s not in the current version, so I’m guessing that you added that. If so change the
https, and the font should start working.
As I mentioned before, what caused the problem to suddenly present itself, was switching to HTTPS. Now that’s a good thing, as all current browsers will warn users that your site is insecure without that. But, in your case, switching to HTTPS broke the site.
Now, will upgrading to the latest release of Rapidweaver fix the jquery problem? I would think so, but that’s a pretty big jump (two major releases) so you might bump into some other issues. Since you are going to do it anyway, then you might go ahead and purchase the upgrade. You can run both RW6 and RW8 on the same Mac, the old project files would get converted when you open them in RW8, but the old RW6 files should still be untouched and available to use with RW6.
You can also try to update the RW6 to the last version of RW6 by grabbing it here.
