Using mediawiki 1.31 and Math extension REL_31

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 "":)

If i change it to allow code 0:

I get

Failed to parse (Conversion error. Server ("") reported: "Cannot get mml. Server problem.")

Is the RESTBase server down?

No, but maybe the Mathoid service is? (talkcontribs)

My Math extension have been failing with the same error since a few days. (talkcontribs)

I've had this problem too. After some debugging, it appears that PHP's curl was refusing the SSL certificate of . I downloaded a cacert.pem file and pointed edited the php.ini to point to under under variable curl.cainfo and openssl.cafile. This fixed my problem.


curl.cainfo = "C:\PHP7\cacert.pem"

Since today I have the same issue. Where did you download the cacert.pem file?

We have the same issue as OP. Adding certificates to php.ini did not help.

Our problems started after a system update. The issue is probably caused by changes in other packages.
