When I used this code
$desc = mb_substr( $desc, 0, $strip_desc, "utf-8" );
[…] dots are not added at the end.
I tried to add to the shortcode read_more="1"
bu it didn’t help.
My shortcode is:
[srr_feed urls="https://natives.chat/c/chinese/25.rss" count="9" show_desc="1" show_thumb="1" strip_desc="70" read_more="1" rich_desc="0" add_nofollow="1" open_newtab="1" thumbnail_position="cover" read_more="0" thumbnail_size="350px" color_style="card" display_type="grid" grid_columns="3"]
