My host (a friend of mine) upgraded his server yesterday. Now, I am getting
[Unknown column 'Array' in 'where clause']
SELECT cat_ID FROM wp_categories WHERE category_parent = Array ORDER BY cat_name
in some wordpress windows when it should have been displaying categories. The host told me that the error log had
First argumented is expected to be a valid callback", And â€œcall_user_func_array()
in the error logs. He said he thought it was a PHP upgrade issue. I can't be the first to see this! What happend and how do we fix it?
Note that this didn't happen right away. The blog seemed to continue running fine for a while. I log in today and it's fried.
