Category Page Breaks after 12 products added

[webbs462]

This is a strange problem. I can't add more than 11 products to a particular category. Also, naming them is a problem. 

Hard to explain over email, but a workaround I'm trying is creating multiple categories and assigning only 11 products to them.

https://formalfashionsinc.com/dresses/empire-style-dresses-1/empire-style-dresses-3.html (works)

But, if I add one more product to either of these categories, the page breaks and you get the below:

NOTE: The above image is from the parent category that the other two pages are on and it breaks.  I don't even have products assigned to it.

I'm at a loss.  I've tried adding a new category and I get the same thing. I've flushed the cache, reindexed and nothing. 

PHP 7.3

Magento 2.3.5-P2

Any ideas?

Hi @webbs462 ,

Try to switch first your website in developer mode so that we will get exact error on browser.

https://devdocs.magento.com/guides/v2.4/config-guide/cli/config-cli-subcommands-mode.html

Else check do you have anything logged in var/log/exception.log file which relate to error

Hope this helps you!

Thanks for the reply.  I went into Developer mode, cleared cache and refreshed the page.  Same error, nothing new.

No, there's nothing in the exception.log file about this, only something about an email template: [2020-09-10 16:55:04] main.CRITICAL: Email template '' is not defined. {"exception":"[object] (UnexpectedValueException(code: 0): Email template '' is not defined. at /home/formalfashionsin/public_html/vendor/magento/module-email/Model/Template/Config.php:225)"} []

Which is something else I have to try and troubleshoot.

Any other ideas to try and find out the error?
