No edit button, and link displayed in editor on adding a drawio diagram

[davethehat]

I have an empty page with a single test diagram:
{{#drawio:TestDiagram2}}

Displaying the page shows a placeholder saying simply:

TestDiagram2
empty draw.io chart

No drawio edit button is present. When I load the visual editor I see a template section for the drawio content, and then a link as follows:

TestDiagram2 empty draw.io chart

<a id='drawio-img-href-1915653392' href=''><img id='drawio-img-1915653392' src='' title='drawio: TestDiagram2' alt='drawio: TestDiagram2' style='height: auto; width: 100%; max-width: 0; display:none;' /></img></a>

I'm running mediawiki in docker, and have visual editor, code syntax highlighting and SVG support enabled:

Any thoughts as to what might be happening?

OK - so this is down to the drawio extension and VisualEditor not playing nicely together. It would be awesome if they did: are there any plans to work on this?

Well, I have the same problem now, using mediawiki 1.33.1 - someone now how to fix this? :)

[davethehat]

in our environment this seemed to be down to whether the user was logged in or not. If logged in, Visual Editor and drawio worked nicely for us.

I have the same problem so I can't use the extension at all. With no edit button how can the editor be invoked?

Mediawiki 1.35
PHP 7.3
MariaDB 10

Same issue here. It worked for months. Now I can only see my already created images/drawings, but there's no edit button any more :-( Any help?!

[tuxedo0801]

Tried to debug this a bit. Seems that the DrawIO JS is not loaded at all?!

LocalSettings.php still contains:

require_once "$IP/extensions/DrawioEditor/DrawioEditor.php";

is this no longer sufficient or what?

[update]

The only thing that has changed in last months: PHP Version and switch from MySQL to Maria DB.

Still using MW 1.30.0 and DrawIO Extension 1.0 ...

Updating to DrawIO Extension 1.1 - see download from https://www.mediawiki.org/wiki/Extension:DrawioEditor did not solve it (caused more problems), also using the github latest version also did not help

[tuxedo0801]

Found out it relates to

        /* check for conditions that should or will prevent an edit of the chart */
        $readonly = (!$wgEnableUploads
            || (!$img && !$wgUser->isAllowed('upload'))
            || ($img && !$wgUser->isAllowed('reupload'))
            || $parser->getTitle()->isProtected('edit')
            );

Looks like one of the conditions tends to false which let readonly be true ... will further investigate.

[update]
oh, damn... found the issue. I protected the page to "admin only", that caused the edit-button to disappear.

oh, damn... found the issue. I protected the page to "admin only", that caused the edit-button to disappear.

I also experienced the "no edit button" but my user guide was on a locked admin only page.

After removing the admin lock, the extension works (mediawiki 1.27) and I have visual editor installed also.

Marking the page with draw.io extension admin-only-move doesn't effect it. Working, thanks @tuxedo0801!
