On August 29, 2024, I am running the current high watermark of Dokuwiki:

Wiki Upgrade
DokuWiki 2024-02-06b "Kaos" is available for download.
You're currently running DokuWiki 2024-02-06b "Kaos".
Your current DokuWiki is already up to date. No need for upgrading.

Today I installed firefox_2024-08-29_09-50-45

When I tried displaying an SVG (known to display correctly), I get the following error message: firefox_2024-08-29_09-46-08

I tried reinstalling firefox_2024-08-29_09-53-21

and the same error occurs:

I reproduced the error by clicking the Preview button during an edit of the playground page and captured the following error messages:

Also, if I "Disable" the plugin, then my playground page renders; however, the SVG file at the end (see below) does not appear and that is the expected behavior since there is no SVG handler within Dokuwiki.

This is the text I'm using as a test in the playground page:

====== SVG Testing ======
{{:playground:sle_airportdiagram_from_nw1_dl20240426-4.svg|}}
restlessminded commented 2 weeks ago

Any way you can attach the .svg file for testing? It appears from the first error that the file isn't parsed because of the 10 MB XML file limit. I want to see if I can take care of that by setting a LIBXML_* flag, but I need something that large to test against.

I have staged the SVG file, SLE_AirportDiagram_from_NW1_dl20240426-4.svg, which is 592 Kb at: https://flightmonitor.org/img/SLE_AirportDiagram_from_NW1_dl20240426-4.svg
