Hi,

I am using multisite component. Everything is working fine but i have upgraded php version to 5.3.10 , all of a sudden admin panel multisite component section went blank.
I have tested the same in my localhost with php 5.3.8 version. It is working fine. Provide me solution for this. Also if possbile provide me the patches.

If you have blank screen, this probably mean that you have a FATAL PHP error.
As you mentioned this is related to PHP 5.3.10, you can probably find a "error_log" that provide more information concerning the PHP Fatal error.

To give you a solution, we need to be able reproduce it and please give us the detailed information concerning the PHP Fatal error that you have with PHP 5.3.10.

Remark: PHP 5.3.10 is at "End of live".
The latest PHP version is 5.3.13

Where can i find the logs . Currently i have opened controller.php and gone to the template function and added error_reporting(-1);.
I got the below things.

Strict Standards: Only variables should be assigned by reference in /local/apps/rxapi/apache/htdocs/sc17/administrator/components/com_multisites/controller.php on line 248

Strict Standards: Only variables should be assigned by reference in /local/apps/rxapi/apache/htdocs/sc17/administrator/components/com_multisites/controller.php on line 249

Strict Standards: Declaration of JFTP::get() should be compatible with that of JObject::get() in /local/apps/rxapi/apache/htdocs/sc17/libraries/joomla/client/ftp.php on line 1459

Please provide me solution for this. Frontend of the site is working fine. Also from admin end i can able to access check patches and settings.

Strict notification is NOT an error but just an information.

So this is not the reason of the Fatal error and blank screen.

As in the path I see something like "htdocs", I suppose you have a specific location where the log file is store.
With cPanel, this is generally the "error_log" file.
Ask you hosting provider where the PHP log file is stored.

Sometimes this is located in a "logs" directory like
/local/apps/rxapi/apache/logs or log

You can also disable the STRICT notification message in the php.ini
They provide plenty of flag to enable/disable the level of error reporting.
In production (live), it is recommended to disable all the error displayed upon screen.
