line 429 in that function is $value = trim( $value );

any solution how to fix ?

function:

What is exactly line 429, is it under default or username?
And the best way to detect errors is to var_dump $value under each of these two lines above.

This site is using a hacked database of W junction

[JmZ]

looks like hes passing an array which should be a string, but im not sure.

[Gaurav]

try doing var_dump($value); die();

just above the line that causes the error.. and then proceed with debugging..

[deliteblogger]

I saw in other threads that you do php things. I can't believe that you don't understand:

expects parameter 1 to be string, array given

[devNULL]

i do, i know that error but its like something that cant pass via that function and i cant understand why.

[l0calh0st]

Well I can translate it for you "expects parameter 1 to be string, array given" means "You are passing an array, but it requires a string. So please god dammit pass me the string."

[soft2050]

function validate_value( &$value, 

remove the &

I don't think so. He is passing the value by reference.

i do, i know that error but its like something that cant pass via that function and i cant understand why.

Paste the lines where you are using this function if this isn't still fixed.
The problem is likely the same as above told.
