Where can I find the code to translate the “Written by (Author)” to my language?

Hi!

I use child-theme Vaaka, but I’m sure that i should search help here.
My site: https://www.ajkub.pl

I want change few things in Saga theme, but I haven’t idea how to do it. For sure, I need to change some css lines, but which?

My requests:
1) I want center site name and site description (it should works on every screen size).
2) I want change menu from drop-down to normal menu in one line.

Both changes should look similar to this theme: https://www.ads-software.com/themes/match/

Sorry for my language skill ??

The Widgets menu is not appearing under Appearance.

Does Saga have Widgets / Sidebar support?

If so, any idea why it isn’t appearing.

Your great theme has a very weird summary support.

It doesn’t support neither <!–more–> (in main field) nor excerpts (separate field). It “cuts” entire text to summary in random / preselected place. That’s quite wrong, because in my case most introductions are broken in half producing very unusable content and end result.

Plus: you are adding three dot (…) AFTER space. This is incorrect in most modern languages. This is correct in most languages, that I know:

Unfortunately you shouldn’t…

This is incorrect in most languages:

Unfortunately you shouldn’t …

Your theme currently renders in second option.

Any chance for a fix for these things?

All my posts’ feature images are far bigger than 1100 x 500, but they still don’t show up no matter what I do. I’ve tried using even bigger images for my previous posts, submitting new posts with feature images after installing the theme to see if those ones would show up, and even seeing if there was something in the CSS that was turning them off somehow, but nothing works.

(Also, there’s an ugly gray border around my header image, even though it’s exactly the recommended size. Any idea what to do about that?)

Featured images don’t show in this theme. I installed the most current version of the theme and it looks nothing like the demo. Featured images don’t show in posts and the overlay-text that is supposed to display on the post’s image on the homepage, that overlay text isn’t showing either. The WP version I’m using is 4.1.1 and there is only one plugin active on the site, the Subtitles plugin.

I uploaded a screen-capture of the posts so you can see how they actually appear on the homepage; they don’t display like the demo at all.
