CRITICAL Allowed memory size of 536870912 bytes exhausted

HI, Yes I’ve already done that, I googled and noticed that.

The code from Roxy didn’t have the M, but I have added that in already.

define(‘WP_MEMORY_LIMIT’, “1024M”);

So now I get this error which is slightly different (after I added the M)

[23-Mar-2023 10:44:10 UTC] PHP Warning: Use of undefined constant ‘WP_MEMORY_LIMIT’ – assumed ‘‘WP_MEMORY_LIMIT’’ (this will throw an Error in a future version of PHP) in /home/#/public_html/wp-config.php on line 79

It now says WordPress memory limit 1GB in the System Status.

That would be reflecting what I just added in the wp-config then I assume?

Thanks

I will have to check the logs tomorrow and see if that fixed the Memory exhausted issue.

Also the WordPress backend is still very slow. I thought that may have helped fix that when we edit a price of product in “QUICK EDIT” takes at least 10-15 seconds to save which is very long.

What could be causing this?

Thanks

Kristin

Hi @kristinubute ,

Ah, I realize that I forgot to add the M in my response here, sorry about that!

[23-Mar-2023 10:44:10 UTC] PHP Warning: Use of undefined constant ‘WP_MEMORY_LIMIT’ – assumed ‘‘WP_MEMORY_LIMIT’’ (this will throw an Error in a future version of PHP) in /home/#/public_html/wp-config.php on line 79

It seems that this is still being added incorrectly – like this: define(‘WP_MEMORY_LIMIT’, “1024M”);

If so, please can you remove that, and add this: define('WP_MEMORY_LIMIT', '1024M');

You will see that we need to replace “ with '.

I must add that this does require advanced knowledge, so if you are not comfortable editing this on your own, I would strongly suggest asking your host to make these changes for you.

It now says WordPress memory limit 1GB in the System Status.

That would be reflecting what I just added in the wp-config then I assume?

Correct, this is a result of increasing your WordPress memory limit.

Also the WordPress backend is still very slow. I thought that may have helped fix that when we edit a price of product in “QUICK EDIT” takes at least 10-15 seconds to save which is very long.

Not necessarily. A slow load in the backend could be due to various factors.

Here are some helpful articles on how to fix a slow loading site:

• First things to consider with WooCommerce & speed
• WooCommerce Slow Site Fixes

Cheers!

Yes I had removed the double quotes and it displays and shows 1GB in the area. But editing products still takes up to 25 seconds to save a “QUICK EDIT” for pricing only .

We are currently using PHP 7.4.

I wasn’t sure if I try to upgrade to PHP 7.8 whether we will have website issues so I haven’t been game.

Hi @kristinubute ,

I hear your concern.

Before updating your PHP version,?you can test the latest version on a local environment?— like?WAMP,?MAMP?or?LocalWP.?Then, when you’re ready, you can go ahead and implement the changes on your production site.

You can read more about this here.

Cheers!

Hi, Checked the error logs and got the same issue even with 1GB WordPress Memory Limit added. This came on the error log this afternoon.

What now?

2023-03-24T03:27:25+00:00 CRITICAL Allowed memory size of 1073741824 bytes exhausted (tried to allocate 398127000 bytes) in /home/#/public_html/wp-includes/PHPMailer/PHPMailer.php on line 3407

This is getting bit frustrating..

Hi, I also see that the latest memory error is different from my original I added about 1 month ago when I added the ticket.

CRITICAL Allowed memory size of 536870912 bytes exhausted…. was the original ticket ..

now it says CRITICAL Allowed memory size of 1073741824 bytes exhausted (tried to allocate 398127000 bytes) in

Is there a common issue with this file wp-includes/PHPMailer/PHPMailer.php on line 3407

I’ve had the issue for over a month now and client is NOT happy. I need to somehow fix the issue. Any other ideas please ?

As the Critical memory error seems to be with the PHPMailer/PHPMailer.php. What is that and what is causing this?

As I’ve already increased this define(‘WP_MEMORY_LIMIT’, ‘1024M’);

Am I supposed to do the PHP.ini file also? or just one or the other?

As Admin backend is quite slow also, which memory limit helps with the Admin area please?

If I have to add the PHP.ini file do I just add 1 line of code and that’s it?

memory_limit = 256M ;

I can’t do that from within the Cpanel PHP settings area?

I’ve also been doing some googling and found https://www.ads-software.com/support/topic/php-fatal-error-allowed-memory-size-exhausted-5/

Under Server section check the values reported for:

• PHP memory limit
• PHP memory limit (only for admin screens)

Under WordPress Constants section check the values reported for:

• WP_MEMORY_LIMIT
• WP_MAX_MEMORY_LIMIT

So under my “WORDPRESS CONSTANTS” my client site says

WP_MEMORY_LIMIT 1024M

WP_MAX_MEMORY_LIMIT 512M

Should the WP_MAX_MEMORY_LIMIT also be 1024M ?

No-one has mentioned about this, I just found it in google.

I can’t understand WHY my client is having this issue when they have been on the same hosting plan and not had issues before. We redesigned only part of the website and new plugins and Theme so this is strange.

Thanks Kristin

Hello,

Sorry to hear that the issue is still present.

To take a closer look, please share a copy of your site’s System Status Report: You can find it via WooCommerce > Status. Select “Get system report” and then “Copy for support”.?

Thank you.

HI

Here is my system report. I have updated all plugins. I have followed all your steps.

I have increased both of these also.

WP_MEMORY_LIMIT 1024M

WP_MAX_MEMORY_LIMIT 1024M

Client has had same server hosting for years, but only recently having issues.

Hosting say it is NOT their end.

ALSo it is the memory exhausted – and only seems to be related to the wp-includes/PHPMailer/PHPMailer.php?

What is PHPMailer and HOW can I fix that specific memory exhaustion?

Is it to do with Cron jobs? Or HOW can I fix this?

Hosting people are hopeless to support and help and put it right back on me to fix it!

I found this whilst googling

https://whmcs.community/topic/297340-allowed-memory-size-phpinfo-issue/ (may not be relevant).

Hello,

Thanks for sending the system report.

WC Database Version: 7.2.0 Please be sure to update your database, you can do it under WooCommerce > status > tools > update database.

Then, I’d recommend performing a conflict test: https://woocommerce.com/document/how-to-test-for-conflicts/

Also, you can install a?smpt?plugin, in order to better debug the issue.

Hope this helps.

Hello,

Same issue here. Would you please let us know whether we should do both of the following methods, or one of them?

Edit your wp-config.php file
Add this to the top, before the line that says, “Happy Blogging”:

define(‘WP_MEMORY_LIMIT’, ‘1024’);

Edit your PHP.ini file
If you have access to your PHP.ini file, change the line in PHP.ini
If your line shows 64M try 256M:

memory_limit = 256M ;?Maximum amount of memory a script may consume (64MB)

Thanks
