hello,
i have my site’s default page layout set to right sidebar and all my posts set to full width, but none of my posts are showing in full width (i even tried setting my default for the whole site to full width, but that didn’t work either). when i clicked on a post before today, the post would show in full width. please help.

Hi Jessie,
I hope you are well today and thank you for your question.
I visited the posts on your shared site and they are displaying full width for me as shown in the attached screenshot.
The images added in the posts are not displaying full width because you have added the images less in width. You should add images having width at least 1050px.
Best Regards,
Movin
hi movin,
thank you for your quick response. i hope you are well.
we have all our photos uploaded at a width of 1000 px. previously, when i clicked on a post, all the photos would show as 1000px across (full width–almost the full length of the text, which i know is 1050 px). please see the attached screen shot that shows the photos in the editor page as full width; this is how they used to look on the actual page as well.
now, on the published page, they are showing at about 1/2 the width of the text (see the attached screen shot of the published page). something changed, and i’m not sure what. how do i go back to having my photos displayed as their actual size (1000px width)?
thank you,
jessie
It seems this is happening because of the Jetpack plugin Photon module that you are using on your site so could you please try temporary deactivating it or its Photon module on your site if you are using it?
This jetpack photon module is not updating the images stored on wp.com so to resolve the issue either disable this module or update the images on wp.com by contacting jetpack support team.
hi movin,
i disabled the photon module and that fixed the problem. thank you so much for your help!! have a great day.
