We have this weird issue on one of our websites.

When customers try to buy something they get an error 500 when they complete the order, the order is registered but they get an error 500 and no email is sent to the customer.

This also happens when a new customer is registering, so when they hit submit they get an error 500 and the registration is stored in Magento.

We also get error 500 in Magento when we try to click on the "reset password" button.

The reason why I think it has something to do with emails is that all of these actions should trigger an email to the customer. However, We have tested the email and it works.

This is what i get in the error logs:

  • Your email template that’s managed in Magento’s Admin is having variables or ‘directives’ {{depends xyz}} inserted that are no longer valid in Magento’s new version. This happened to me when I upgraded my version of Magento from 2.2 to 2.3 . Magento remembered to upgrade everything but the old email templates and I had to edit them manually to be compatible. I found the solution by googling the error about “Depend Directive email error after Magento upgrade”. Sorry my answer could be better but it’s ~2am and my phone’s about to die 😲. Oct 12 at 8:48
  • Hi, Thank you for the quick response. I did look into what you wrote, but the thing is that we have 5 websites and it is only 1 that has this issue. As I can see all of the templates were made before we upgraded from 2.3.3 to 2.3.6, so we should have seen this issue on other web pages. Oct 12 at 12:54

I had this same problem.

Although I don't have access to your store to evaluate your specific case, here are some hypotheses that I encountered when working through this on my own store(s).


Keep in mind: Template issues don't have to exist directly in your top-level email template.
The issue can manifest when a child template contains the issue that is being called-in from your top-level template.
Nonetheless: Be confident that all template issues can be resolved within Magento's Admin and do not require changes to the codebase.


Hypothesis #0

In the footer_template shown in your Question. There is an inconsistency.

In the first usage of {{trans ''}} regarding store_phone, it looks desired:

{{trans '<a href="tel:%store_phone">%store_phone</a>' store_phone=$store_phone |raw}}

However, in the second usage of {{trans ''}} regarding store_hours, the syntax looks malformed. It seems the opening trans ' after the opening brackets {{ is missing:

{{<span class="no-link">%store_hours</span>.' store_hours=$store_hours |raw}}

Hypothesis #1

You need to close your template tags!

{{depend some_var}}Some Content{{/depend}}

In my codebase, this was noticed on email templates containing {{template config_path="design/email/footer_template"}} because the footer template we created in Magento's Admin didn't close a depend tag {{depend store_phone}} with a corresponding {{/depend}}.


Hypothesis #2

A non-existent variable or a variable containing no data.

Although I wasn't able to test this other hypothesis at the time, I became suspicious that using a variable for which there is no data for could also cause this error even if your template tags are properly terminated. However this would be such a silly oversight by Magento that I became doubtful it could be related to the issue.

For example, I thought this could throw an error when I didn't have my phone number saved into Magento Admin's store configuration (at path general/store_information/phone):

{{depend store_phone}}
    Call us: {{store_phone}}
{{/depend}}

  • Hi, Thank you for your detailed answer. As i can see from the error message it seams to be a depend tag that is not closed as you say. But I can't seem to find it. I have edited the question with the footer code Oct 12 at 19:21
  • After looking at your footer_template content, I've updated my answer with another hypothesis. Oct 12 at 19:35

    Thank you so much for your help!!!!! You are a savior, I did not see that at all.... And it was like you said after I added trans before <span it worked again, how could I have missed that Oct 12 at 19:50
