Bug Home page WOL caching error

[craiglathrop218]

I happen to be running 4.1.4, but this issue has been ongoing for a while. I get the following error in the logs every time the cache flushes (either manually or auto).

[Fri Jun 10 12:15:06 2011] [error] [client 63.210.163.226] PHP Fatal error:  Call to a member function query_read_slave() on a non-object in /var/www/vhosts/performanceboats.com/httpdocs/vboptimise/cachers/cacher_forumhomewol.php on line 37

It results in a "server error" page and only affects the CMS pages. The forums work fine. I am using filecache at the moment (I know, but in my defense we are running 15k drives).

I've been unable to confirm this issue on either 4.1.3 or 4.1.4

Forum Home WOL also shouldn't affect the CMS, as the code referenced in the error does not execute on any CMS pages.

Found the issue. I had a widget on the home page showing the WOL. Removing the widget removes the problem.

If for some reason you would like to debug this particular issue I have a video screen capture of the problem and can give access to the site for debugging. I think that if you add the WOL widget to the CMS home page you will likely be able to replicate the issue.

For the moment not a big deal on my site. The WOL thing on the home page wasn't exactly critical.

Edit: If I had to bet I would say that the home page stays broken until someone visits the forums and creates the WOL cache. We have a very active forum so this typically happens within 10 seconds. That would explain why no one has experienced major downtime. PM with link to screen capture sent.

Yeah the widget probably isn't cached, I wasn't aware there was one.
