I just noticed a similar problem after moving to 2.0.2 with the evopress skin.

When I click on a category link, I get

An Unexpected error has occured!

Additional information about this error:
Output format [] not supported.

When I switch to a different skin, the problem disappears. I would theorize that this is an evopress issue, or more accurately, an issue between the Categories widget and the evopress skin.

Where do I find the code for the Categories widget?

inc/widgets/widgets/coll_category_list.widget.php

I got one installation 2.02 working and using evopress skin, but i have the same problem using skin custom index.main.php, anyone have any idea on what to do ?

i really have to fix this..

buzzworkers & chashock : links to the blogs where this is happening would be useful ;)

also the widgets wich shows these links :

* Recently
* Archives

Page list widget in any position give a blank space.

You definitely have something wrong with your custom skin, because when I switched it to the evopress skin all of the links worked as expected.

You might like to try re-downloading the install zip and uploading the whole of the skins folder again.

I'm going to split these posts off into there own thread as they appear to be a different problem.

Yup i just found also that this is a skin problem, the thing is the custom skin i'm using is the one from the default installation..but i'll do some more research to find out, i 'll follow your advice, re-uploading the skin might do something

Looks like you've got it working ;)

Yes indeeed :)) the folks at work where already stress !
my custom skin was a mix of the old custom 1.12 and 2.02
Thanks for your advice ! it's working perfect !

This blog is behind a firewall that I can't let you through to view. Sorry, but thanks for the help!

I hadn't made a single modification to the evopress skin, but I decided to take the suggestion and unpack that folder from the original 2.0.2 archive file, and amazingly enough, it fixed the problem. Our categories are once again working just like they should.

Thanks for the quick responses and suggestions!

Reinstalling the evocamp skin hasn't worked for me. There's definitely something wrong with it.

The same kind of links work fine using the evopress skin.
