When you try automatic upgrade for WordPress, you might get this error:
“Allowed memory size of 33554432 bytes exhausted (tried to allocate …)”
This can be solved easily by changing the setting:
Open file wp-settings.php, on line 13, increase the memory to bigger one like:
“define(‘WP_MEMORY_LIMIT’, ’64M’);”
This should fix the issue. If not, please also make sure the setting in php.ini is big enough:
“memory_limit = 128M”.
