[SOLVED] community builder links do not work

Dear Sir
i built my site using
Joomal: 2.5.6
Cb: 1.8.1
and it works fine till yesterday , suddenly i recieved an error message when trying to acess the site (error 500 internal server error) i contacted my hosting company and they solved the problem , now i can access the site (only the home page) but all community builder links do not work , i can not register, view profile,....
i contacted my hosting company again but they replied that this issue is related to joomla or comunity builder , after enable the debug mode found the following errors
Strict Standards: Only variables should be assigned by reference in ...\components\com_comprofiler\plugin.foundation.php on line 3623

Strict Standards: Only variables should be assigned by reference in ...\components\com_comprofiler\plugin.foundation.php on line 3624

and a list of similar errors

i googled about that and according to my search i did the following
updated my php.ini file as followed:
error_reporting = E_ALL
and
display_errors = Off

but did not work
any help will be very appreciated

heba

Dear Sir
i tested the site again today, and ...it works, do not how and why , but it works , may be the changes in php.ini required ´time to be effetive .
thank you
