I installed WPMU on hostgator, everything is fine except I can not add new site in wp-admin/network/sites.php
I installed the fresh WP4.2.2 with default WP theme, no plugins activated.
I faced this errors
Warning: preg_match() expects parameter 2 to be string, object given in /home1/xxx/public_html/wp-includes/formatting.php on line 3435

Catchable fatal error: Object of class WP_Error could not be converted to string in /home1/xxx/public_html/wp-includes/kses.php on line 1038
The screen is dead at this.
I contacted with hostgator support staff but they can't solve the problem.
Can someone give me a suggestion please?
I really need to get the site works properly.
Thanks,
