After i change PHP version to 7.1 i dont see errors on login page.

But i i try clear cache i still have error:

Fatal error: Uncaught Error: Class 'Tools' not found in /classes/db/Db.php:794 Stack trace: #0 /config/alias.php(48): DbCore->escape('configuration', false) #1 /config/alias.php(53): pSQL('configuration') #2 /classes/Configuration.php(155): bqSQL('configuration') #3 /classes/Configuration.php(209): ConfigurationCore::loadConfiguration() #4 /classes/PrestaShopAutoload.php(171): ConfigurationCore::get('PS_DISABLE_OVER...') #5 /classes/PrestaShopAutoload.php(130): PrestaShopAutoload->generateIndex() #6 [internal function]: PrestaShopAutoload->load('Tools') #7 /config/config.inc.php(85): spl_autoload_call('Tools') #8 /admin/index.php(42): require('/var/ww in /classes/db/Db.php on line 794

Did you add memcache server IP Address?

I supose you have already looked at this!!! it seems that it also depends on server cache functionality, the question is if activating it has more beneficts than problems associated with it!!
