Upgrading from 3.1.5 to 3.1.6

Hallo everyone, I am Owino from Kenya, East Africa.

I have been using CI for a while now, but I am still stuck at version 3.1.5.

I am sure I have never understood the step 2 at https://www.codeigniter.com/user_guide/i...e_316.html

What I get after I am done with step 1 is

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 262144 bytes) in /var/www/html/mysystem/system/core/Loader.php on line 218

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 262144 bytes) in Unknown on line 0

I need your help

The correct way is to edit your php.ini file. Search for 'memory_limit'. You may find 128M which is a default value. Increase this 512M or more as required. Restart the apache server. You are good to go.
