post appear larger than original size

Looks like it is in the settings. Can you try adding another new post to see if the earliest one goes to a thumbnail display. It looks like you have two featured posts then the rest will be thumbnails.

I added two another post. no difference. It must be in settings->writing or in general but there isn’t! It’s crazy

Can you try this

Apperance>Theme Options >Blog Pages

Set the Full posts to display to 0

Ya this is my another problem!
Appearance->Themes and Appearance->Themes options don’t work and
when click on it appears: “Content not found” or “page not found”
I think I had it but now there isn’t. maybe I do somethings wrong. But I installed Pinboard theme
Do you know why?

If you have not made any customisations to the code I would reinstall the theme. If you purchased the theme you can install it from the zip file but I find the best way is to FTP it to your server.

I have version of 1.1.2 and there is and update for it. Do you think it would solved with upgrade to 1.1.4?
Actually one of my friend installed it and did some customisations. but I can’t install the theme.
Thank you so much for your help.

If you update to 1.1.4 your cusomisations will be fine as long as you upgrade from your Dashboard.

No. ?? This is from dashboard:
Please Note: Any customizations you have made to theme files will be lost. Please consider using child themes for modifications.
Do you think “Appearance>theme” will comeback with upgrade?

I upgrade theme to 1.1.4 but appearance>theme still doesn’t exist
