was php 4 now

I have upgraded to

PHP : 5.2.5

still using

MySQL : 5.0.45-log

Now getting this warning in publish plug and same warning frontend register page

Warning: Call-time pass-by-reference has been deprecated; If you would like to pass it by reference, modify the declaration of array_unshift(). If you would like to enable call-time pass-by-reference, you can set allow_call_time_pass_reference to true in your INI file in /home/content/x/x/x/xxxxxxx/html/candidates/administrator/components/com_comprofiler/library/cb/cb.session.php on line 41

Thanks for the help!

In cb.session.php found array_unshift ($check, &$_SESSION);
changed to array_unshift ($check, $_SESSION);

All is working.

Again, thanks for all the help!

Hi there!
I still have the session write error message after changing the 41 line in the code.

It is strange because in my local machine I do not get that error but with the exactly same code and database running in the server I get that error.
And it is something to do with the captcha because when I disable the plugin I do not get the error.
