I've read the other posts about this issue, but mine is different in one fundamental way... there is no function defined in the error. It reads like this:
Warning: call_user_func_array() expects parameter 1 to be a valid callback, function '' not found or invalid function name in /home/ovbar/public_html/wp-includes/plugin.php on line 496
I've never seen this error without a function defined so I'm at a loss. I moved it using the
All-in-One WP Migration plugin. Any ideas? Here's what I've done so far:
- I've already checked for hard-coded urls just to be sure, and there aren't any.
- Deactivating all plugins still shows this error.
Every other aspect of the site works fine. This error only displays on the front end.
