I enabled theme debug on my drupal 7 installation using drush vset theme_debug 1, But Now I can't disable theme debug using drush vset theme_debug 0, What the wrong, Is there any wrong or mistakes in the drush command above?

I also tried to comment out $conf['theme_debug'] = TRUE; in the settings.php and then replaced with $conf['theme_debug'] = FALSE; but none works.

Any help and suggestions on this issue?


  • Do you have file local.setting.php?

  • Hi @Jonh, Thanks for quick replying. I don't have local.setting.php. I can see there is a file called default.setting.php & setting.php in sites/default directory.

If using drush vset theme_debug 0 doesn't work. Try disabling the theme debugging on your settings.php file, adding the below line of code:

$conf['theme_debug'] = FALSE;

Don't forget clear the cache.

  • Thanks for your suggestion, I actually did that but NO LUCK. You can check my question description where I mentioned this. However, I may messed up everything, getting a lot of error log message.
