Look like a bug in Markdown syntax component which fail to load for some reason in your instance (or in the new 11.3 in general) and block the loading of the list of syntax components in this page.
Would be great if you could report it on https://jira.xwiki.org/browse/MARKDOWN with all the elements you can think of so that we try to reproduce and debug it. An important thing to do is to click on the red boxes you get and copy the whole content of the error you get.
Just tried the following:
… and it worked fine…
@anandhaibs Anything you did differently?
What we really need is for you to click on the red message and to copy paste the full stack trace.
nop sir…
i followed the same way

Sorry for the delay…
This is the root cause. However it’s not normally possible 
The Markdown Syntax 1.2 provides it (https://extensions.xwiki.org/xwiki/bin/view/Extension/Markdown%20Syntax%201.2)…
For a reason I can’t imagine, it means the extension is not properly installed. Maybe it didn’t finish installing or you deleted some files on the filesystem or… I’d recommend uninstalling Markdown Syntax 1.2 and installing it again.
Thanks
-Vincent
Before doing this could you copy paste the progress log you get in the Extension Manager for the Markdown Syntax 1.2 please? See https://extensions.xwiki.org/xwiki/bin/view/Extension/Extension%20Manager%20Application#HProgressLog
Thanks
Hiii

@tmortagne Any idea what can have happened? There’s no error in his logs.
ok so that’s definitely wrong, it’s missing a lot of things
Maybe @anandhaibs installed an uninstalled it several times in which case the dependencies are already there in the last install log.
@anandhaibs have you tried to restart since the last time you installed the markdown extension just in case ? Maybe there is some classloader issue. Also when you do make sure to check the startup log for any extension related error, maybe some extensions are conflicting.
Hii @tmortagne
when i install the markdown extension in first time i get some error (see the first screenshot)… and then i uninstall it and install again… but still there i can see the same error but it is minimized
see the screenshot
current error log
OK, so that’s the reason why the last install log does not contains the dependencies.
yes…
So how can i solve this problem?
Sorry no idea for that part, it seems to be a Markdown extension bug.
Is Markdown extension essential for jira management in Xwiki?
There’s no relationship between the JIRA Extension and the Markdown Extension.
I’ve closed https://jira.xwiki.org/browse/MARKDOWN-60 because I don’t see how it can be a Markdown extension bug. The error just means that the EM didn’t do its job properly for some reason and the code isn’t there in the classloader.
What I’d do is remove the extension, cleanup the extension manager local cache in the permanent directory and try to reinstall it.
