Registration error


when im trying to register using an existing email then instead of receiving the error message about “this email is in use… etc’ ‘

im receiving the following error on the top of the screen:

Parse error: syntax error, unexpected T_STRING, expecting ‘,’ or ‘;’ in /home/bizid/domains/ : runtime-created function on line 1

and above the Email Field:

Warning: call_user_func_array() []: First argument is expected to be a valid callback, ” was given in /home/bizid/domains/ on line 339

it happens even when i use the default theme , or any other theme , when i use English or hebrew ,

nothings helps…

also i have another problem when trying to install a plugin i always get “connection timed out” any idea? im using wordpress and wordpress MU in many sites without ever receiving these errors before…

Thanks in advance for any assistance!
