[SOLVED] PHP Fatal error - cb.core.php

Hi,

I've bought an extension: extensions.joomla.org/extensions/structure-a-navigation/site-map/24063

which produces a dynamic site map.

Everything is ok and the HTML site map is generated until I don't log in, if I log in and click on the site map link the whole site disappears, nothing, a blank white page.

I've been in contact with the support of Jsitemap and my hosting and after 2 days of investigation this is the error which causes the issue:

PHP Fatal error: Allowed memory size of 50331648 bytes exhausted (tried to allocate 7680 bytes) in <span>/</span>home<span>/</span>mainaccount/public_html/mysite.com/components/com_comprofiler/plugin/user/plug_cbcore/cb.core.php on line 462

Could you suggest any solution please?

Thank you
Regards

You're hitting your 48mb memory limit. There's nothing wrong with that particular line of code (it's only using 7680b). Increase your PHP memory limit to 64mb and you should be ok. Joomla + CB it self will consume roughly 30mb. Add in other extensions and that grows quickly.

Hi Kyle,

memory_limit is currently set to 512M, before yesterday it was 256M. We've even done some test with hosting's support team and they've proofed to me that my current memory limit is 512M.

Thank you for your offer, any other suggestion will be really welcomed.
Best regards

If PHP is reporting 48mb, then that's your memory limit no matter what phpinfo or your host tells you. When configuring php.ini for memory limits you should place it in Joomla root and root/administrator so it can properly apply to frontend and backend.

I've done the following test: magazine.joomla.org/issues/issue-dec-2010/item/295-Are-you-getting-your-fair-share-of-PHP-memory

and it showed the memory limit is 512M.

How to see what the PHP is reporting?

As for the php.ini file currently it's in the root of my cpanel' home directory and not in the root of public_html directory where the joomla site is. Should I move it to the public_html directory or copy it there? Also, actually this particular site in a subdirectory which is in the public_html, should I move or copy it to the subdirectory?

Thank you very much Kyle
Best Regards

That test only runs for the current location. php.ini in hosting root doesn't always properly apply to sub directories. It should be in your Joomla root and root/administrator.


Allowed memory size of 50331648 bytes exhausted

50331648 / 1024 / 1024 = 48

This means your memory limit is 48mb. Always trust the exhaustion error over anything else as it's the most accurate.
