We are using markdown 1.1 as default syntax

Could you please help in solving this issue?

thanks,

Best Regards

Did you try to restart ?

Any idea if you are using the latest version of Markdown extension ?

vmassol · March 3, 2020, 9:24am

You seem to be using Markdown 1.1 which is not recommended. Please user version 1.2: https://extensions.xwiki.org/xwiki/bin/view/Extension/Markdown%20Syntax%201.2 (which is recommended).

Thanks. Let us know how it goes.

maharshi.vyas · March 3, 2020, 2:26pm

I installed the markdown 1.2 syntax and it seems to help (partially, as images in the page are not visible. I can see them in attachment).

But I need to change the each page’s syntax to 1.2 one by one

Is it possible to do in one attempt?

Note that I can reproduce this issue and the JIRA issue to track it is Loading...

vmassol · March 3, 2020, 3:29pm

Yes it’s possible, see Loading...

maharshi.vyas · March 3, 2020, 5:42pm

I can confirm that the workaround works for markdown 1.1, I can access all the pages without any error.

I have not tried the conversion to markdown 1.2 with the automatic method yet. I will try it.

Thanks a lot for the help

Also, this issue on JIRA seems to be still happening Loading...

My wiki-test instance where I installed, restored, and upgraded from 8.2.1 to 11.10.3, it works fine. I do not have above error.

But on a fresh instance that I did today, I had the above error where url/link Application items is localhost.

https://localhost/xwiki/wiki/lcsbbiocore/view/Dashboard/ (this fails as it tries localhost)

https://mydomain/xwiki/wiki/lcsbbiocore/view/Dashboard/ (this works)
