Dear Rui,
I just upgraded to version 2.5 and i use a self made image as menu icon. I have the image 50×50 pixels, this is large enough, in the past this looked great, but now for some reason the image is stretched out and looked fuzzy.
Yes i tried to add a new post to a blog page within my website. The media does add to the library, but for some reason when i click on add media when making the new post nothing happens…
https://www.seveba.nl/wordpress/header/ this is the header i used, but it showed realy big on computer screens and really small on phones. I would like something simular, but with the ability to adapt to screensize.
