I have the solution. This may help some of us:

In includes/CategoryPage.php, find : and replace by :
And the 3 columns will have the same width

I did tests on Monobook, and the problem comes again. The problem is not the skin. In fact, when the title of a page is long and in the first column, it appears on one line and shaking up the size of other columns ... Has anyone already encountered this problem on mediawiki? Thank you for your help ...

Yes I have adapted the style, but only by changing colors in the css.

Hello, I have a small display problem with my categories. When I click on one of them to see which pages are listed, they are placed oddly. The titles of the pages are divided into three columns, but it is as if the first was 50% and the other two 25% and 25%. http://images4.hiboox.com/images/1509/b...

Sorry, I was absent several days. Thank you very much for the reply.

On Monobook, when someone write on a page of discussion, the "discussion" word turns blue in the tab. With Gumax 123, is it possible to obtain a showy color for this tab when there is a discussion ?
Thank you

Yes, that's what I thought. We must wait. In fact, it's coming?
Thank you very much for all!

Ok, a new version of the skins will be available soon. In my case, I made many changes in the skin 123 (color, size, font ...). To avoid having to redo everything, could you also indicate the small changes to make?
Thank you in advance.

I have the same problem with Gumax 123 (all the new links are blue). I don't understand what to change in the gumax folders. Thank you to help me.

I found it! This works in MediaWiki:Gumax.css
Thank you
