Hello, I have a group with more than 4,000 registered users. When I try to create a discussion within the group, I get the error message below:

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 512 bytes) in /home/public_html/libraries/joomla/registry/format/json.php on line 67

How to solve?

Hi samanet,
Please contact with hosting server provider by asking such help to increase "memory size".
Thanks

What is the ideal size that recommends me to memory capacity?

Hi Samanet,
According to the error message it says the limit is 128MB.
So I suggest you to increase to 512MB.
Thanks

Hello, I have increased all values ​​below 512 and the error persists.

php_value max_execution_time
php_value upload_max_filesize
php_value post_max_size
php_value memory_limit
php_value set_time_limit

Hi Samanet,

the solution for that, you must increase the memory limit. Here Jomsocial recommendation:
documentation.jomsocial.com/wiki/System_Requirements

please try to increase php_value memory_limit again to higher number.

if still can't, please provide me administrator access detail by editing your first post at this topic and put it at site info form.

Regards,
Albert
