I cannot use Artio because of this.
The problem with Joomla is that there are so many different pieces of software made by so many different people. They are at different stages and do not interact smoothly all of the time.

I am running the basic Joomla SEF.
This works with Joomfish
I am also running a property letting software Jomres.

I had a problem that the Jomres images for properties did not show up - this means whatever it causing this must come off the site.

I would love to use Artio - but until it works well with Joomfish I will have to settle for the basic SEF package.

I agree Joomfish is a very significant piece of software and exemplifies the international collaborative nature of Joomla. It is a pity they don't mesh yet.

I spoke too soon -
The site does not function normally with core SEF activated.
Well it is intermittent- images render sometimes with core SEF activated.

The latest Joomfish went on general release tonight.
I installed this on a J1.5.6 site which was running well with Joomsef.
Apache 2 server
php 5.2.5
Joomart template - Teline II

The result of putting Joomfish on the site was virtually all the images fail to render.
Images appear when the url is in the pre-Joomfish state but when there is es/fr/eng is in the url the images fail to render.

I took Joomfish off the site and everything works fine with core SEF and Apache mod rewrite switched on.
I took Joomsef off the site with Joomfish on - everything works fine.

Am I missing something - I liked the way Joomsef did things but I also want the language functions of Joomfish.
