Post preview in the main page is not showed

Hi,

Please paste your website URL. The problem can be identified easily through source code.

Thanks,

I have checked the problem, its strange that its hiding all your content. Please give me a screenshot of your content editor that how you have used the post splitter in your content.

I created two sited with same content.
https://mordik.com/ – jQuery Post Splitter installed and activated
https://mmmmmmk9.bget.ru/ – jQuery Post Splitter installed, but deactivated

Post edit page: https://storage4.static.itmages.ru/i/15/0915/h_1442298416_7284655_fdf7fbbd3a.jpg
jQuery Post Splitter settings:

Click on post name and you will see that its working fine
https://mordik.com/bez-rubriki/link.html

but on listing page it will not work because its related to content. You have to use excerpt for the listing page. Make sure that your listing template is calling the function the_excerpt() instead of the_content().

Excuse me, where can I find that part of the code that needs to edit?
In “functions.php” file of template?

it should be your content-single.php, content.php, page.php, content-page.php etc.
