Warning message: A non well formed numeric value encountered

@makiaho

Are you using php 7.1 ?

Also check the php.ini for the value set for memory_limit.

Hi,

yes I am using 7.1.1.

PHP Memory limit is 2024M

@makiaho

As a workaround change the 2024M (shorthand notation) value into a true integer 2122317824 (bytes) in the php.ini and then retry.
Or formulated differently, don’t use shorthand notation for memory_limit in the php.ini file.

It seems as of PHP 7.1.x a value like 2024M is treated as a string.
So you cannot use it for calculations.

The iTSec plugin set_minimum_memory_limit() function needs to be adapted to take this into account.

@makiaho

On second thought, the workaround will only fix 1 of the 2 PHP notices …

Thanks, actually in the PHP.ini -file there is given these values:

; Resource Limits
memory_limit = 512M
max_input_time = 60
max_execution_time = 30
max_input_vars = 20000

However, when I used BWS-plugin for checking the system status, I got these values:

Environment
Operating System Linux
Server Apache / ZoneOS
Memory usage 16.77 Mb
MYSQL Version 10.1.21-MariaDB
SQL Mode NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
PHP Version 7.1.1
PHP Safe Mode Off
PHP Allow URL fopen On
PHP Memory Limit 2024M
PHP Max Upload Size 2047M
PHP Max Post Size 2047M
PHP Max Script Execute Time 30000
PHP Exif support Yes ( V1.4 )
PHP IPTC support Yes
PHP XML support Yes

I was not able to edit the php.ini file so I asked help from the SP (Zone)

@makiaho

What version of the “BWS-plugin” (Better WP Security ?) are you using ?

BWS stands here for BESTWEBSOFT PANEL ??

But the version of the Better WordPress Security plugin is 6.1.1

Ah ok.

2024M seems a bit like a strange value … (2048M makes more sense to me).
Anyway the memory limit can be set in many different places:

– WP_MAX_MEMORY_LIMIT constant in wp-config.php file.
– .htaccess file.
– Other plugin code …

Thanks, I’ll try to set that limit somewhere else. So is the problem (only) that somewhere(?) it is used a string (like 2024M) instead of integer and it cannot be parsed?

Hi,

this is a bit weird.
I am not able to modify nor remove the php.ini dedicated for that URL. However, SP (Zone) told that I am able to override it by creating a global php.ini.

Now there is the original php.ini with a line
memory_limit = 512M

and the ‘global’ php.ini with a line
memory_limit = 512000000

The error exists. When I use BWS-plugin for checking the status, I’ll get these values: PHP Memory Limit 2024M

And also a lot of warnings “Warning: Illegal string offset ‘WP Refresh’ in /data03/virt55765/domeenid/www.MySite.fi/htdocs2/wp-content/plugins/captcha/bws_menu/bws_menu.php on line 216”
The line 216 is

$system_info[‘active_plugins’][ $plugin[‘Name’] ] = $plugin[‘Version’]; //LINE 216

I also added a new plugin: Simple System Status and it gives me a bit different values: see the bold concerning on this.

### Begin Simple System Status ###

WP Version: 4.7.2
WP_DEBUG: Enabled
WP Language: fi_FI
Multisite: No
WP Memory Limit: 128MB
WP Memory Limit Status:
<b>Notice</b>: A non well formed numeric value encountered in <b>/data03/virt55765/domeenid/www.MySite.fi/htdocs2/wp-content/plugins/simple-system-status/views/output.php</b> on line <b>80</b>
Not OK – Recommended Memory Limit is 64MB

@makiaho

Yes. The set_minimum_memory_limit() function in the core/class-itsec-lib.php file generates the 2 notices on the following lines (when using M shorthand notation):

$memory_limit *= 1048576;

$new_memory_limit *= 1048576;

In PHP version < 7.1.x multiplying by eg ‘256M’ was not generating a notice.

Changing the value set for memory_limit to bytes prevents the first notice.
But it does not prevent the second notice.

To prevent the second notice from happening you would also need to change the call being made to the set_minimum_memory_limit() function in the iTSec plugin code.

It’s only used in 2 locations. For creating Database Backups and for File Change Detection scans.

The original call looks like this:

set_minimum_memory_limit( '256M' );

And it should be modified to:

set_minimum_memory_limit( 268435456 ); //=256 megabytes in bytes

However there is no point in changing plugin code as any changes will be undone after the next iTSec plugin update.

@makiaho

PHP Memory Limit 2024M (Probably the value of PHP memory_limit. But I did not check the code.)

WP Memory Limit: 128MB (Downloaded the SSS plugin and checked the code. Turns out this is reporting the value from the WordPress WP_MEMORY_LIMIT constant, which is something different).

So this explains the different values. And therefor these 2 values cannot be compared.

Create a simple PHP script (show-mlimit.php) and run it(https://www.yourdomain.com/show-mlimit.php):

<?php
echo ini_get('memory_limit');
?>

This will tell you exactly the current value of memory_limit set by the PHP config.
Any other value displayed in BWS plugin output is probably set somewhere in the WordPress env.

Deactivate and delete the Simple System Status plugin.
You don’t need it and it is preventing us from focusing on your main issue.

@pron

I removed Simple System Satus plugin and created the script:
“<?php
echo ini_get(‘memory_limit’);
?>”

The value given by the script is 512000000
