Fatal error when accessing posts
I host my blogs on hostmonster and just upgraded to version 3.1-RC3. I can log into my blog through WordPress, but when I try to access the posts I get the following error:
I am very new to WordPress and don’t have much experience with PHP. I was able to fix a couple errors in the PHP code after the upgrade, but I researched and can’t find a solution to the following problem.
Fatal error: Call to undefined function: array_intersect_key() in /public_html/blog/wp-admin/includes/class-wp-list-table.php on line 274
If anyone can tell me how to fix the code I would appreciate it.
