Hello,

I disabled the plugin and it works. Not sure if it's a good fix but for now it seems the rest of the site is working without the plugin enabled.

Maybe you could contact ARK editor team support to report this bug, as they may be able to fix it!

I think it's related to joomla "content" rendering, used by Joomla articles, but too used by some other extension to render content using Joomla framework (to allow to include third party content plugin, such as Phoca Gallery for example).

iCagenda is using content for full description of each event (so that could explain the issue, maybe they manipulate data before rendering based on com_content (Joomla articles) and not other extension that could use content item.

Hope this will help...

Best regards,
Cyril
