Topic on Talk:Structured Discussions

I tried to edit description on my talk page (zh:User talk:Gakmo) but encountered error message when I want to edit the wikitext saying Parsoid error. When I want to save, the message below appeared. How can I fix it? Many thanks.

[404f2474] Exception Caught: Conversion from 'html' to 'wikitext' was requested, but core's Parser only supports 'wikitext' to 'html' conversion

Hi Gakmo

What kind of text did you tried to add to the description?

Hi Trizek. Simply cannot save any edit, which gave the following error:

[f62f910d] Exception Caught: Conversion from 'html' to 'wikitext' was requested, but core's Parser only supports 'wikitext' to 'html' conversion

When I check the history, I find the following error message:

[6e9ac0dc] 2015-10-23 16:00:34: 类型“Flow\Exception\WikitextException”的致命错误

I've filed Phab:T116685 for the developers to investigate. Thanks for the report, and sorry about the problem.

After much investigation, this led to a fix in the 'core' mediawiki (https://gerrit.wikimedia.org/r/#/c/249050/), so special thanks to you, for helping the devs to find a years-old bug, in code that everyone believed to be infallible. :-)

(I'll update again, when your specific usertalkpage is fixed.)

Many thanks!
