Why does the visual position of the posts on the page go astray?

Question

Blogs

Greetings!
cms wordpress, the theme is "portal", I modify it for myself.
problem areas - index.php, archives.php (page of all records, page of categories)
20 records are placed on the page (2 lines of 5 pcs), then there is a transition to the next. page.
When I publish the 9th entry, it gets confused and displayed as in the picture:

When adding the last 10th entry, everything lines up as it should:
PS: In the original topic, the number of entries per line was 3, but they were larger in size. I reduced the value in the "width" parameter in the .exserpt class to 17.6%, and 5 records fit in length.
Since there will be many entries, the bug will always be repeated on the ninth entry.
Please help me find the cause of the jamb.

Answer 1

You have a non-constant block height (due to different number of title lines).
To make sure everything works, give them a temporary .exserpt { height: 240px; } .
