Reply To: Category filter issue

@ Janick

Looks like a plugin conflict. Notice when you select a category the page looks like it is loading twice. Something, a javascript from another plugin, is causing that flicker. My guess is sometimes the width for the category is be calculated right at when the page is “blank” so it is be set at a zero width.

I did notice that JetPack is not working for you. Well at least the Photon module (I think).

I suggest trying the plugin conflict test.

There is a lot of javascript be loaded on the page, so just about anything could be causing the page flicker, maybe even the theme.

Hope this helps, let me know.
