I just installed and activated Allvideos.  It shows up fine on the item editor but it is not displaying video.  It is also giving me this warning. 

 

Warning: preg_match() [function.preg-match]: Unknown modifier 'a' in /home/content/m/9/8/m982532/html/libraries/phputf8/str_ireplace.php on line 40

 

Any ideas on where to start troubleshooting this?  Thanks in advance!
