Hi,

Apologies if this isn’t the right topic.

I’ve upgraded from 15.07 to 16.04, added my missing indices and I’m now attempting to remove this error:

“The PHP memory limit is below the recommended value of 512MB”

I’ve run php -v and confirmed:

PHP 7.3.5-1+ubuntu16.04.1+deb.sury.org+1 (cli) (built: May 3 2019 10:00:05) ( NTS )
Copyright © 1997-2018 The PHP Group
Zend Engine v3.3.5, Copyright © 1998-2018 Zend Technologies
with Zend OPcache v7.3.5-1+ubuntu16.04.1+deb.sury.org+1, Copyright © 1999-2018, by Zend Technologies

Altered this file:

/etc/php/7.3/apache2/php.ini

And set the following:

; Maximum amount of memory a script may consume (128MB)
; http://php.net/memory-limit
memory_limit = 1024M

After restarting apache2, I still see the memory warning. I can see this type of error over the forums, but no clear solution as some are using snap (which I’m not) and some others haven’t found a solution.

I didn’t see this error before I upgraded

Any help would be greatly appreciated

Hmm. That worked for me. Not sure why it wouldn’t for you. Run this command:

locate php.ini

To find other instances of the php.ini file - it might give you a clue as to what’s going on and/or what you might change? Possibly the cli version?? Good luck.

Hi @charlienz,

Are you using php-fpm?

fist do php -v to verify witch php your using.

Then, accordingly, modify your php.ini in ALL section.
To avoid config being erased at each upgrade, create local.php.ini files if needed.

Sometimes, an apache2 stop/start ( not a restart or a reload !!! ) don’t even work.
Reboot may be nescesary

Locate returns:

When I look at the PHP version selected:

Php -v

Scrap this, ran an apt autoremove and it’s good now. Suspect something may have been lingering

Ok. Good.
You have 3 versions and 7.3.5 is the good one

Usually, the good php.ini are located under:
/etc/php/7.3 and then /apache2 /cgi /fpm /cli
Modify All four php.ini

Apache2 restart… Sometimes a reboot is needed
