Yes that's exactly what I said... The CSS for footnotes is not being loaded.
Your file is 65+KB in normal mode, and 64 967 bytes when Turbo is enabled. There's probably something that prevents Opera from loading more than 64KB worth of data (including headers I guess) in Turbo mode. You'll have to contact them... Or try to set up Turbo to work correctly on large files.
Or just move your useless CSS to the end of the CSS file.
Thank you, Nao!! I moved the footnotes CSS to the beginning of the file and now footnotes are displaying correctly in Turbo mode, so size matters! I've also minified the css file and it's now just 46,244 so there shouldn't be any problems.
I did look for settings for Turbo mode but there aren't any other than "on", "off" and "automatic".
BTW your site's fixed toolbars --- brrr... Do you really like THAT? And your website link here is 404 (has an extra s at the end)... And I think the cookie message should be removed (eh), or at the very least, shown using something else than the dreaded SMF loading message styling... And I think your homepage has too many blocks and silly animations... Then again, portal-like sites were my love a dozen years ago. Even the homepage on wedge.org is too heavy-loaded for me now... And you didn't come for design advices.
The fixed menu bar was requested by several members and it does aid navigation but I agree, it's a matter of personal preference.
My posted link gave you a 404? Umm, I've just clicked on the links - both my original and where you quoted it - and they work just fine. Not sure what's happening there.
In many respects I agree with your critique of our portal, it is a bit "busy" but it is what the site owner wants. I thought the slow scrolling display of (Aeva) gallery items is a little less boring than simply a stic display of 3 or 4 pictures. I'd prefer them being a bit bigger and without the thunbnail border but that would require resizing each picture's preview and add considerably to the load time. At least there aren't any awful flash animations!
The Cookie Acceptance panel.... yes, well.... I do agree with you and one day I might actually know enough CSS (and/or Java) to make it a bit more presentable. On the other hand, its gaudiness does draw your attention and makes you want to click on "I accept" just to get rid of it!!
Thanks for your assistance, I really appreciate it - and welcomed your constructive criticisms too!
