+
+### Solution:
+
+This happens when your session.save_handler php parameter set to some another session storage that "files" (redis, memcached etc.), to fix that you need 
+to edit your php.ini and set 
+
+{% highlight PHP %} 
+session.save_handler = files
+{% highlight PHP %} 
+
+session.save_path can be just disabled for use default parameters or set to valid folder in your file system 
+
+{% highlight PHP %} 
+;session.save_path = /some/patch/here
+{% highlight PHP %}
