Critical Error since update to version 7.6.0

Hi,

I’ve a memory limit of 126M (don’t know if this is important).

That’s quite few. try to up to 512Mb. And yes, this important if you have plugins or script which are “memory hungry”.
However, it would help if you gave us the exact error.

Best regards

Hi @joy0114

thanks for yor answer. I activated the debug mode in the wp-config file and it now says the following:

I know that the host package of my friends website only has 128M PHP memory limit. I need to call the host if its possible to increase that. There was no change in the backend of wordpress at tools > website health, when I changed the value to 512M in the wp-config file. What I can’t understand is why woocommerce in the status tab says “WordPress memory limit 512 MB”. Is this a different memory size than the php memory size?
At server environement there is no size for the whole php memory listed. I only have:
PHP post max size: 60MB
Max upload size: 60 MB.

Sorry, this is the first website I create with WordPress and I have no experience with woocommerce or server settings.

Is there any more information you need?

Thanks a lot!

Hi,

I think you have the explanation here:
Allowed memory size of 134217728 bytes exhausted

“WordPress memory limit” is php memory size. At least, Wordress considers that this memory is for “him”.

As a matter of fact, you only use 128M. That’s not enough.
Minimum would be 256, and best 512Mb.

You see in “website health” what you declare in wp-config.php.

The “truth” is in php.ini
It would be interesting to see the result of page called whatyouwant.php which contains:

<?php
    phpinfo();
?>

or :

<?php
    phpinfo(INFO_VARIABLES);
?>

Best regards

Hi @juliaeme

To clarify, did you follow the recommendations provided by @joy0114? Let us know what was the outcome in your case.

You can check this documentation to increase the memory limit: https://woocommerce.com/document/increasing-the-wordpress-memory-limit/

Let us know how that goes for you.

Hi @joy0114,
hi @ihereira ,

thanks for your fast and successful help in this case and sorry for my late answer. I was on the road, so I couldn’t check your solutions…
BUT: I had a conversation with the hoster of my friends website. He increased the php memory limit for testing to 256MB and the error was gone ?? So it seemed that @joy0114 directly had the right guess!!!
We will now buy an upgrade for the php memory limit.
You could not believe how much you helped me… I have a few more gray hairs because of that ??
I am very grateful to you!!!!

@joy0114, I don’t really know, what I should do with the php.ini. Can you explain it, if I still shall do something here?

Best regards from a very happy Julia

Hi Julia,

I’m glad you were able to find a solution.

Don’t you worry with php.ini.
I told you to create a php page containing phpinfo() in order to display what you can specify in php.ini, just for confirming you only use 128M for php memory.

But, it’s already an effort to get 256M, I’m afraid it will be even more difficult to be allowed to configure your own php.ini …

Glad to have helped you.
Best regards

Hi @juliaeme ,

Really glad to hear that the issue is no longer present!

I will go ahead and mark this as resolved then – feel free to create a new topic if you need further help ??
