Fatal error: Out of memory (allocated 13893632) (tried to allocate 2 bytes) in /users/,,,,,,,,/public_html/includ

Thanks for the quick reply . I don't have access to php ini file and also i have renamed .htacess because my school site doesn't appear when the htacess is enabled( I get only a page with warnings) I have only one choice, to add the code in settings file(better to ask where should i put it) The server that host my files has the php safe mode on . For the time being they can't change this settings for the server because is provided by the educational ministry for school webpages.
I will try the only choise that i have and then i will provide the feedback. I am thinking also to upgade to last release 6.9

I didnt get such message again. Perhaps the hoster increased the size in the ini. If will appear again i will review the steps .
But today i got another strange think while trying access the blocks administration page . I get this
Fatal error: view::destroy() [function.view-destroy]: The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition "views_plugin_display_default" of the object you are trying to operate on was loaded _before_ unserialize() gets called or provide a __autoload() function to load the class definition in /users/pel/1dim-giann/1dimgian/public_html/modules/views/includes/view.inc on line 1460

Please help me - its high priority issue and don't understand what happened

I will - Thank you for your help

Arie I had a report from user that had the error appeared again . I 've added the line ini_set('memory_limit', '32M'); in sites/default/settings.php (as i dont have any other choice) but when opening the status report from administration I see that in server is set to :PHP memory limit 48M . Thus my setting have to be higher . What do you suggest to do
