Hi,
This means that there is something communicating with the outside and it can't. So it waits for an answer until the timeout, but the timeout is bigger than the "max execution time" of your PHP.
It could be a plugin, like for example the QuickBooks plugin, which communicate the details of the order to the accounting system servers.
Most likely, it's because of the sending of the notification emails. That's the most common issue: HikaShop is sending the email to the email server but the email server is either not responding or responding too slowly.
So there are several things you can do:
- disable the emails in System>Emails and see if it helps. If it does, then it comes from the email sending and you need to check with your hosting what's going on.
- check your mass actions. If you have any mass action with a trigger "after/before an order is created", disable them and see if that helps. If so, then there is a problem with how the mass action is configured.
- check the plugins you have installed which can do things when an order is created. See if you have any which need to connect to some outside server.
It's not likely this comes from HikaShop itself. Otherwise, others would have the issue and it's been 2 months the 4.6.1 was released.
