Things are still a bit in construction at the time. I haven’t been able to import the posts from my previous Joomla! installation, although you can still find it at http://www.panic1.be/joomla untouched. I’ll look into getting those articles in here soon.
I’m also having problems with the icons in the edit window, and I’ve seen some graphic errors here and there. Must be something with the themes that went wrong. I’ll look into that too.
I have fixed the graphical errors and the visual editors missing icons by uploading the wordpress sources to my webfolder again, and it works now (after Ctrl-F5). Now I just need to start looking into transferring those posts from Joomla!.
* another update
I have finally found a script to transfer all posts from my old Joomla! installation to this WordPress. The package I found first didn’t work with the 2.3 version of WordPress, so that explains the delay. This new package can be found here (I have also attached the script, README file is included). I haven’t converted the comments, but since they were so little, I won’t bother too much.
