error on Category Page - Prestashop 8.2.1

[emilien]

Hello,
I have problem on category pages in PS 8.2.1 after debug on:

"Notice: Module litespeedcache returned an array on hook actionProductSearchAfter. This is not allowed, the response must be joinable to a string. in /home/srv35305/domains/multi-click.pl/public_html/classes/Hook.php on line 1007 "

Have someone fix this issue ?
Is is after installing ls-cache. It is also after disable caching in plugin settings.
If disable plugin - there is no problem.

Have someone fix this issue ?

Disable the PS developer mode, purge the cache and try again.
