TeX parser error in SU(2):
Fehler beim Parsen (Konvertierungsfehler. Der Server („http://mathoid.svc.eqiad.wmnet:10042“) hat berichtet: „Error:["TeX parse error: Double subscripts: use braces to clarify"]“)
Same error with
<math>\overline{M}^1</math>
Appears only with MathML, not with MathJax or PNG images.
I checked
./texvcjs '\overline{M}^1'
+{\overline {M}}^{1}and
./texvccheck '\overline{M}^1'
+{\overline {M}}^{1}as well as
./texvcjs '{\overline {M}}^{1}'
+{\overline {M}}^{1}So the error message seems not to come from neither texvcjs nor texvvccheck, which seems strange.
This needs to be investigated further.
I just tested with the most recent version of mathoid:
curl -d 'q=\overline{M}^1' mathoid.testme.wmflabs.organd received

Can someone who has access to the production cluster test if the request
curl -d 'q=\overline{M}^1' mathoid.production.address
works as expected of if it returns the double subscript error
^^ seems to be fixed indeed
