Extremely slow ttfb on one specific page caused by Brizy_Admin_Templates->templateFrontEnd()

Hi.

I have a specific page https://fitnessreloaded.com/try/ that needs 12-14 sec just for the server to start delivering the page (time to first byte.) This page is using the "Trial" Brizy template.

https://gtmetrix.com/reports/fitnessreloaded.com/Z8YTJggm

In fact, it's so slow, Google Page Speed Insights times out when you put in this url.

This does NOT happen on other pages made with Brizy, just this one.

I contacted my hosting company and they reviewed:

"The overall CPU usage it's a normal state and WPX Cloud is caching the pages correctly.

Here is the result, after analyzing each of the pages:

[1] - Testing the "Try" page https://fitnessreloaded.com/try/ returned the following results about Brizy:

Brizy_Editor->wordpressObjectCreated() - brizy/editor.php:206 - 0.0039s
Brizy_Admin_Templates->templateFrontEnd() - brizy/admin/templates.php:383 - 14.7783s

From the test, we can see that the specific Brizy function "Brizy_Admin_Templates->templateFrontEnd()" from file "brizy/admin/templates.php" takes ~14 seconds to generate the page.

[2] - We have performed the same test on the homepage https://fitnessreloaded.com/ and as expected the result for the same function "Brizy_Admin_Templates->templateFrontEnd()" is much lower, less than a second:

Brizy_Editor->wordpressObjectCreated() - brizy/editor.php:206 - 0.0045s
Brizy_Admin_Templates->templateFrontEnd() - brizy/admin/templates.php:383 - 0.0319s"

Why does brizy/admin/templates.php take 14 seconds to load that page?

For troubleshooting, I've already given you my credentials on a private support request that is still open as a ticket.

Looking forward to your response,

Maria
