Varnish configuration not working

Question

I have been installed varnish module in drupal 7 while clicking on configure it shows an error page with title server error and if i come back to module menu there was another error log

like Warning: require_once(/var/www/magz/sites/all/modules/varnish/varnish.admin.inc): failed to open stream: No such file or directory in menu_execute_active_handler() (line 515 of /var/www/magz/includes/menu.inc).

I tried reinstalling and some other stuffs but the error is still there is there any solution for this

Answer 1

Did you checked if the path and file (folder) is valid? seems that the module requires certain file which are not there.

I've checked with version: 7.x-1.0-beta2 and no such issue occurred.

Just to close out that the read permissions would cause this, please follow the instruction from that: page - regarding access rights setting.
