Note that this occurs with 3.7 beta and 3.1 vbseo also when I disable all hooks via config.php the error disappears,
and when i disable vbseo ONLY the errors disappears. I tested this myself using a google bot headers test (browsers are ok - googlebot gets it 500 when vbseo is there)
So its vbseo. Any ideas how to fix this??
pretty pissed that i lost a pr of 5 on my forum and 4000 pages after noticing this... (i guess thats what you get when using beta software with vbseo) google webmaster tools shows more than 4000 error 500 pages for the forum since i installed vbseo 3.1...
