问题
I transferred the web directory of a site to new hosting. after importing the directory and the DB, I got this error:
PHP Fatal error: Allowed memory size of 536870912 bytes exhausted (tried to allocate 79 bytes) in /mnt/stor12-wc1-ord1/895923/www.youth-panel.com/web/content/libraries/joomla/database/database/mysql.php on line 712
I found my .htaccess file that was empty and added the line
php_value memory_limit 256m, and it didn't work, I changed it to 512m, which is the highest that they support and still doesn't work. Can someone help me please.....Never thought a site transfer would be this difficult.
so I added the folloing to .htaccess php_value memory_limit 512M php_flag display_errors 1 php_value error_reporting 8191
RewriteEngine on RewriteBase /
and I get the following

I will try turning off those plugins to see what happens
回答1:
Your current configuration allocates 512 MB of RAM to your PHP scripts. I don't know about you, but my server has 12 GB of RAM available. This means that if only about 20 people tried to run that script of yours at the same time, my server would thrash and die.
Consider fixing the memory problem in the code, rather than blindly increasing memory limits. Personally, I would recommend setting the max memory size to something restrictively small, such as 16MB, to force yourself to write more efficient code - works for me!
回答2:
You may try to add this at the top of the code
<?php
set_time_limit(0);
ini_set('memory_limit', '-1');
?>
But it is highly suggested that you should check your code and make it efficient to use less memory.

Two possibilities -
First, you need to increase the value of "memory_limit" in php.ini.
Second, you could have a problem with your code that is allocating too much memory.
