Hi, if i enabled Fetch items from children categories in k2 content module i get PHP Fatal error: Allowed memory size.
I have set memory_limit is to 1024M on php.ini.
Joomla 3.8.6 and k2 2.8
Thanks

Hello,
Can you post the exact error please?
Also selecting the exact categories you want to use is a bit more performant.

Hi,
i selected only the specific category and i select NO this option: Fetch items from children categories. I want only the children of selected category:
Fatal error: Allowed memory size of 1073741824 bytes exhausted (tried to allocate 20480 bytes) in /var/www/dominio.it/libraries/vendor/joomla/registry/src/Format/Json.php on line 67

Fatal error: Allowed memory size of 1073741824 bytes exhausted (tried to allocate 20480 bytes) in /var/www/dominio.it/libraries/vendor/joomla/registry/src/Registry.php on line 85

Funny,

The files that produce the error are core files. 1024MB PHP limit is an overkill and can lead to issues. Can you try using a 128 - 256MB limit?

Now i use 512M and for this issue i tryed at 1024 but i've the same problem.

How many subcategories are there in total?

three

I tried to reproduce the issue with no luck
jmp.sh/ok0XqVu
jmp.sh/6L22zpT

Which version of PHP are you using? Any other K2 related extensions?
Are you using Apache or Nginx?
For the time being you can select directly the three subcategories.
