I was trying to install REDIS and I got HTTP500

[DraganK]

Hi! 

 

Please help. 

I was trying to install REDIS and I got  HTTP500.  No access to Backoffice either due the  HTTP500. 

Only access thru PLESK and SSH

 

Configuration: PS 8.1.2 /  PHP 8.1.31 / Ubuntu 22.04 

 

Log: 

AH01071: Got error 'PHP message: PHP Fatal error: Uncaught Error: Call to a member function getQueryHash() on null in 

/var/www/vhosts/balc.com/httpdocs/classes/db/Db.php:596\nStack trace:\n#0

https://www.balc.com/productos-rebajados?resultsPerPage=99999&q=Marca-

web "balc".com is not real. 

 

db.php 596 is: 

   if ($use_cache && $this->is_cache_enabled && $array) {
            $this->last_query_hash = Cache::getInstance()->getQueryHash($sql);
            if (($result = Cache::getInstance()->get($this->last_query_hash)) !== false) {
                Cache::getInstance()->incrementQueryCounter($sql);
                $this->last_cached = true;

                return $result;
            }
        }

 

How to solve the problem? 

 

Thanks in advance!

Not much idea of the same but you can disable the cache by adding the below lines in the config/defines.inc.php. Add the same in the top.

 

defined('_PS_CACHE_ENABLED_', false);

 

Hope it will work.

Thank you very much!

Finally I had to restore backup. I will try another day to  install it again.
