Description:

I have a custom error page set up for member registration, but when it hits the error page, I get the following error:

Exception Caught
Cannot overwrite TMPL on the loader.
ee/EllisLab/ExpressionEngine/Legacy/Facade.php:83

I’ve tried searching the error, but am only finding stuff about addon development…

Detailed steps to reproduce the issue:
1. Go to this page: http://dev.trulieve.com/patient-account/register/shop, and try to create an account using this already existing email address: .(JavaScript must be enabled to view this email address)
2. Hit submit and you’ll get the error
3. Here’s a screencast: https://youtu.be/FR6IhIJr2co

I have CMS working with other conditions just fine, but it’s this particular form for some reason. I’ve even tried to set it to my default error template (that is working great with other errors) and I get the same error.

Here’s the relevant code that I have in my error page template:

{if csm:error == TRUE AND csm:action == 9}
	
		...... ERROR MESSAGES AND STUFF ......
	
	{if:elseif csm:error == TRUE AND csm:action == 10}
	
		...... ERROR MESSAGES AND STUFF ......
	
	{if:else}
	
		...... ERROR MESSAGES AND STUFF ......
	
	{/if}

What could be going wrong here?

Thanks!
