Smarty errors when cache is activated

[keysoft87]

Hello,

 

I'm having problems when I active cache.

 

Prestashop version is 1.6.1.2. and theme is Leo Universe. The problem started when I install this theme.

 

Logs says these errors and when cache is activated, the website works very slowly.

[error] FastCGI: server "/usr/sbin/php-fpm-domain.com" stderr: PHP message: PHP Fatal error:  Uncaught exception 'UnexpectedValueException' with message 'RecursiveDirectoryIterator::__construct(/var/www/vhosts/domain.com/httpdocs/cache/smarty/cache/b1): failed to open dir: No such file or directory' in /var/www/vhosts/domain.com/httpdocs/tools/smarty/sysplugins/smarty_internal_cacheresource_file.php:196

Any idea to solve it?

 

Thanks
