XCache issues with W3TC

Hi, guys.

I’m having troubles trying to set up XCache with W3 Total Cache plugin at my WordPress (version 4.7.2). Every time I try to activate it I get tons of this error message:

he var cache was not initialized properly. Check php log for actual reason in /home/bitblog/public_html/wp-content/plugins/w3-total-cache/Cache_Xcache.php on line 173
