Thank's for your feedback. I know there are different settings for the categories, because these were set differently to show the problem. As mentioned, the error occurs when I set the number of Leadning Articles to 4. And disappear if I set the number of Leadning Articles to 0.
I can switch, by setting the number Leading Articles to Zero for the first category you mention, and to 4 for the last category you mention, and you can now see that the problem with two missing articles in the last row (or one extra article after the last whole row) has only moved from one category to the other.
At the same time, I do a test for the next category in my main menu, by setting the number of Leading Articles to 3 instead of 4, and keep the number of Intro Articles to 9. With this setting, 4 new rows with a total of 12 items appear every time I click on Load More, not 13 items. But 3 leading articles will be too few, because there will be a void, and 6 leading articles will be too many, when in addition there should be space available for a banner, such as on the front page.
The settings for the number of Leading Articles should not affect the number of new Intro Articles that appear each time a reader clicks on Load More, but it appears that the template is misconfigured, so it actually does.
When it apparently works right with your demo site, it's because 4 Leading + 4 Intro = 8 items, which is divisible by 4, and this gives two new whole rows with 4 items in each, for each time you click Load More. Try setting the number of Leading Articles to 3 or 5, or the number of columns to 3 instead of 4, click on Load More, and you will see negative consequences of the misconfiguration.
Maybe the problem mentioned on this thread, also is related to what was addressed on the thread below? Maybe that problem was not really solved, but just moved to another place?
