All posts with a certain word in it are giving an error

Hi,

I dont know if this is a bug or troubleshooting, I dont know whether we need to squash it or shoot at it (HAHA)... whichever, or both, doesnt matter to me.

1. When making new posts, we had fatal errors (intermittantly)

From a search engine link (*YAY* it was number 1) But the page didnt open, this is what was shown.

Fatal error: main(): Failed opening required '****-******-*****.php' (include_path='.:/usr/local/lib/php') in /***************/16/***********/htdocs/forums/vbseo.php on line 849

*** used To delete out unimportant info.

If you need the full path and information, I will gladly PM.

Both the new posts, and the page that caused this error had the same word as the second word in the title. (Dont know if that is coincidence, or the problem)

Thanks in advance for your time,
Kim
