Warning: Invalid argument supplied for foreach() in /public_html/classes/Hook.php on line 491

[Kst]

Hello,

We got an error at the top of some pages:  Warning: Invalid argument supplied for foreach() in /public_html/classes/Hook.php on line 491.

I've read that it could be a problem with the foreach loop or arrays, but I don't know php and don't know how to fix it. 

In line 491 I find: foreach ($results as $result) {

Another problem is that when I enter a category from the client side, I can't go to the 2nd/3rd/4th/5th page, only one page is displayed and the next ones don't want to load. The error Warning: Invalid argument supplied for foreach() in /public_html/classes/Hook.php on line 491 appears on pages that do not want to load.

I also get an error after enabling debug mode:
PrestaShopBundle\EntityTab.    
The association PrestaShopBundle\EntityTab#tabLangs refers to the owning side field PrestaShopBundle\EntityTabLang#tab which does not exist.

Please help me solve the problem, I am also attaching a picture of the code.
