Blank page when editing in frontpage since Gantry 5.4.0

Hi,
i use Rocket theme templates with the last framework Gantry 5.
Since the release 5.4.0 of Gantry, the edition in frontpage of a flexicontent article give a blank page.
I tried to debug this but i can't see any error message on the blank page.
I tried to activate the maximum error reporting in joomla without success.
I created an issue in Gantry 5 github Here .

But i am not sure that the developpers of Gantry use Flexicontent.

Micker if you read this message, i saw in an old post, that you tested gantry + hydrogene.
Perhaps could you look at this error on your test sites?

If you are confronted with this difficulty, you can fixe this with the reinstallation of Gantry 5.3.9
The downgrade don't cause any problem.

Hello

give me super admin access to the web-site and i should be able to find / print the real error message

Hello Georgios,
i hope you're fine in this end of year.
I sent you the url, the login and pass of super admin.
This test site is a joomla base 3.6.5 with Gantry 5.4.2 and Flexi 3.1.1

If you install the old release of Gantry 5.3.9 , you could see that this problem does not occur.

Thank you in advance for your help.
Charly

Hi Georgios,
i wish you and all the community an Happy new year.
I write this post to be sure you recieved the url, the login and pass of super admin.
I sent all these by private message.

I tested this issue on different servers and with other components (jevents, k2, joomla content) and this occurs only with flexicontent.
I can't understand or find, what is changing the frontpage edition of FC, between Gantry 5.3.9 and 5.4.0 releases

@charlynancy54
It seems to be a bug in Gantry that our code is triggering
till this is fixed you can:

Edit file:
components/com_flexicontent/views/item/tmpl/form.php

Find and remove
you will rarely want to change article ACL in frontend, and removing it , just keeps the current ACL

Thank you verry much Master Georgios.
You are wonderfull :

• you found where was the problem
• you helped the Gantry developer to solve this (i was searching the issues that i opened, but it's already solved thanks to you)
