I think I have found the problem with this and have implemented a fix for it. It seems to have been a woocommerce hook I used that caused a loop that consumed a lot of memory. Perhaps your plugin uses a lot of memory and that together with the hook using a lot of memory exceeded the maximum amount of memory and that caused the 503. I have changed our code to not use the hook that used a lot of memory and now I don’t get the 503.

I’m setting up a staging site to test if it helps to deactivate all other plugins, but it will not be done until tomorrow.

in the log file. This is all I can see in it and I have reproduced the problem just before getting the log file.

Our hosting company is one.com and we are using their largest subscription to get a server with the most memory available(8GB RAM). There is nothing I can do to change that. They don’t have any subscriptions that would change that. I will forward your question to one.com and see if they can do anything about the memory or change the PHP INI file.

Hi,

I got some response.

they checked for the following things and could not see anything wrong on the server end, although there are some improvements needed.

But I don’t see anything that would explain the 503.

Hi,

I can view small orders with the plugin active. It is only when an order has a larger amount of products that the 503 happens. I’m in contact with our hosting company to see if they have access to more logs. I have emailed them several times but so far they have not given me any logs. I can reproduce the problem at any time, and I have checked the fatal error log and the debug.log file before and after reproducing the problem. I get things logged in the debug.log file, but nothing that explains a 503. It is strange since normally a 503 is logged in that file. I have had 503 before and they were logged in that file. I get nothing logged in the fatal error log. There is not even a fatal error log created for the current day. I have reproduced the problem today and sent our hosting company the time and date and hopefully they can see something in the server logs.

Best regards

Hi,

That may be the case on the staging site, but the issue is the same on our live site. I just added the staging site since I can have the plugin active at all times on it and hence I thought that it would be easier to find the problem on the staging site, I can’t have it active on the live site since my coworker can not do their work when it is active. Since the issue still exists on the live site and that has no multi site folder there is still a problem with your plugin making it unusable on our live site.

Best regards

I have a staging site at?https://www.aveo.se/stg_0c734/

Activate the?*Enable Support*?checkbox under?*Remote Diagnostics*
Gives me? “‘Could not communicate with your server. Please contact your hosting provider, or firewall service, or view your fatal logs to resolve issues and try again.”
I get nothing in the fatal logs.

I have activated the plugin on our live site(https://www.aveo.se/) and I do not get the same error when activating(Activate the *Enable Support* ) on that. But I can only have the plugin active for a limited time since it breaks functionality that is essential for my coworkers. Please look at this ASAP.

Hi,

This is still an issue. I have updated wordpress to 6.6.2 and your plugin to 4.4. I still get 503 when I try to view an order with many products in it.

Our server is hosted at one.com and I have contacted them to see if they have another server log or something that can explain why it happens. They said they will investigate and get back to me. I hope they have a better log than the debug.log that I have access to since I did not see a problem in it, which is a bit strange since I believe that I normaly would get something log in it when a 503 occurs. I told them that you would like a full stack trace and maybe they can give me that.

I have reproduced the problem on my staging site.

I get this in the debug.log

But I don’t see anything that would explain the 503 that I get. It is the complete debug.log file after I have reproduced the problem.

It is also strange that it only happens when an order has something like 30+ products, but works fine when an order has less products.

It only happens when I have the plugin active. Could it be that you somewhere call that function or another function that then calls that function and the key is not passed along or is set to null instead of a string. The function expects a key in the format of a string and gets null, which could be a bad function call where the key is not included in a place where it should be. It is not uncommon that an error is triggered somewhere and then reported as occurring in a woocommerce file, simply because one has missed error handling to detect the problem before the code reashes the woocommerce file. I have seen this when I have coded things.

The errors in the log points to

/**

     * Check if an order key is valid.

     *

     * @param string $key Order key.

     * @return bool

     */

    public function key_is_valid( $key ) {

        return hash_equals( $this->get_order_key(), $key );

? ? }
and I guess the $key should not be null since @param string $key Order key. says it should be a string and null is not a string.
