The website encountered an unexpected error. Please try again later.

Hi @corE,

Tank you for reporting the bug.

How did you install the update? Did you use composer? Did you put your site into Maintenace mode before install 8.x-2.15?

The error is referencing new services added in 8.x-2.15: visitors.visibility. It is also refencing another service/class KernelTerminateSubscriber which was removed.

The cache needs to be cleared so Drupal knows about available services. The visitors_update_8216 function will also clear the cache. You should be able to go to http:///update.php to run the update.

I can understand the frustration of a white screen of death. If we put the contents of visitors_entity_view(), in a try/catch, it should prevent one of the errors.

KernelTerminateSubscriber has been removed. I think clearing the cache is the only way to clear the second error.

Thank you bluegeek9;

I installed via admin UI update screen... put into maint mode and cleared cache before update download, but not after. After it downloaded is when I noticed the white screen and did not proceed to update.php. I didn't have time to do much so I just grabbed the error info and restored the old files (ftp). I'll take another try later. My apologies if I reported in error (or if reported a non-issue).

Hi corE,

I was able to fix the white screen of death issue with a try/catch. The KernelTerminateSubscriber error gets logged to Recent messages, but doesn't break the site.

I am testing 8.x-2.16. We added a view counter like the statistics module.
