I'm having two issues with Emphaino on my site, Travel n Dive Blog:
1) Duplicate featured images. If I only insert an image at the top of a post, there's no thumbnail next to the post excerpt on my home page. If I only insert a featured image, the image has no caption, and I have no control over the image size. If I insert both, I get duplicate images, which looks terrible.
This didn't happen to me when I started my blog a couple months ago. Not sure when exactly it changed, but it seems recent.
It actually seems that the duplicate featured image from my post titled "A beautiful Bali sunset..." has disappeared. I'm not sure when or how because before this afternoon, I'd been away from WordPress for a couple months. But the newest post definitely still has them!
2) Thumbnails on my home page are not all the same size. I'm not sure what's happening here. I edited the functions.php a couple months ago because I wanted thumbnails bigger than 150px, but then updated the theme. I realise this means my edit was lost because I don't know how to write the code for a php child theme to replace a function in the main theme.
A post from before the theme update seems to have retained the larger size, but the one I just put up today (backdated to 25th June) is small, which is what is confusing me. Surely once the theme is updated, the thumbnail for the older post should also go smaller again, right?
In any case, what I'd like to achieve is larger thumbnails on the home page without having to re-edit functions.php every time the theme is updated.
I'd really appreciate some help fixing these two problems! Thanks for your time :-)
