Just installed the extension, verified it on Special:Version, added the line to LocalSettings.php. ... but, when I copy/paste the example tabbed table, when I preciew changes on a page, I get the following error:
[ZAZh_vFmkz4WsA0Sv3kZzgABOBY] 2023-03-06 21:58:22: Fatal exception of type "Error"
Is there something I'm missing, or anyone know what the problem is?
