Hi Abie, I think I saw somewhere it was written that it was. Could you guide me please where can I double check that?

Look in Appearance -> Themes Click current them and read detais

I copied this from the Details of my BlogGem theme: "It is fully responsive and works flawlessly on all type of devices like mobiles, tablets, laptops, and computers. BlogGem is search engine friendly. It integrates perfectly with popular SEO plugins like Yoast SEO to create an SEO ready blog. BlogGem is fast, secure and lightweight." It sounds like the ideal theme :D

I guess that means that the theme is fine and the problem is somewhere else......

Yes it is - "It is fully responsive"

Are you using the Kraken Image Optimizer, that comes default with every wordpress ?

Ehm no, I do not have it installed. Shall I install it as well, given that I have EWWW Image Optimiser already? Also is this version good given that it was updated 1 year ago and it is untested for my version of WordPress?

But let me confirm something, so on my Home scroll the featured image looks great on mobile, it is only when I click on the article itself that the image gets cropped. Am I expecting too much?

Let's try to see if we change the plugin there's a difference, your image should be optimized automatically

With Kraken, you can minimize the size of your image to fit page, I haven't worked with EWWW so I wouldn't know.

I have just activated the plugin and there is no change in my featured image :(

Mine same, however active and i am using it

Can you minimize your image with EWWW, if so you may wanna try that.

Go to where the image is, click image pen try minimize.

It looks like my Kraken has some settings issues. Do you know what I shoud include for API Key and API Secret?

I PM ed Keys
