CMS Weird fatal error after add a comment

[محروم.كوم]

Hello: I was testing version 4.0.3 and created an article. Everything was very good (as expected) but after I added a comment the article shows as blank page.

I though that this could be only with the new articles created by myself and I added a comment to 'Welcome to the new CMS' preloaded article and the blank page attacks again!

I look my error_log file and i found this:
PHP Fatal error: Call to a member function query_read() on a non-object in /xxx/forum/plugins/showthread_profile_stories.php on line 7


Do I have to create a ticket or somebody know about this?

PD: I run Suspect File Version and nothing is wrong. __DEFINE_LIKE_SHARE__
