Prestashop 1.7.6.5 Search Returning 404 Page

[GreatWebDeveloper]

Hi 

My siteb is returning 404 when i try to search a product in the search bar.

• I tried rebuilding the index,
• Clear the cache
• Deleted htaccess
• Enabled Search Within a word

But no luck. Can someone help me resolving this?

Well, GreatWebDeveloper, did you set the Debug to On so the error/warning messages can be displayed?

You can pinpoint the issue reading those.

@Rhobur Thanks for your message. Gettng this error 
Fatal error: Access level to SearchController::$search_string must be protected (as in class SearchControllerCore) or weaker in /home/infini11/public_html/override/controllers/front/listing/SearchController.php on line 71

Can you suggest any fix?

[Rhobur]

You need to redeclare that method, /home/infini11/public_html/override/controllers/front/listing/SearchController.php on line 71, as protected, or public.
