Blog Issue: Warning: trim() expects parameter 1 on blog.php
 

Everytime I go to blog.php* I get the errors:

Code:
Warning: trim() expects parameter 1 to be string* array given in [path]\includes\functions.php on line 301

Warning: number_format() expects parameter 1 to be double* array given in [path]\includes\functions.php on line 355

Warning: trim() expects parameter 1 to be string* array given in [path]\includes\functions.php on line 301

Warning: number_format() expects parameter 1 to be double* array given in [path]\includes\functions.php on line 355
How can this be fixed?
