Problem with GNU Radio Wiki

[Ian Bennett]

Good Morning,
	I'm working my way through the tutorials and have come across a problem when viewing 
https://wiki.gnuradio.org/index.php/IQ_Complex_Tutorial
	The message "Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and 
accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server 
"https://en.wikipedia.org/api/rest_v1/":):" is littered throughout the page in bold, red coloured text.
	Since I do see images, I assume they are what the message is referring to but I am not sure. There 
could be information I'm not seeing.
        This happens on my Ubuntu 18.0.4 LTS installation with firefox 89.0 and 
Chrome 95.0.4638.69.
        It also happens on a Ubuntu 20.0.4 LTS VM using firefox 94.0.
        Googling indicates a problem on the mediawiki server.
        Curious as to whether anyone else is seeing this problem.
        Regards,

Ian
