Error 500 open Page Sp Page Builder

Hello Tufiq,
Sorry, I needed a DB to work on another site.
I've just restored the connection, I don't touch anything anymore, I'm impatiently waiting for your news.
Access codes have not changed.
Thanks again.

Hello Tufiq,
Thank you for your feedback but I don't see any change.
SP Pages Builder Pages still not showing in admin.
I always get a blank page when I want to edit one of the pages (:
Unless I misunderstood your explanation.
Then why do you want me to install akeeba backup?
Is it by making a backup and reinstalling it that I will solve the problem?
Yet you tell me you made a change to the htaccess file but I don't see any change.
Thanks for your help.

Hello Toufiq and thank you for your feedback.
I just went to your test server and I still have the same error!
http://helix-framework.org/user/digikult/administrator/index.php?option=com_sppagebuilder&view=page&layout=edit&id=97
The problem is when I connect to the admin/SP Page Builder and I want to edit a page I always get a blank page: HTTP ERROR 500
I even tried on 2 different browsers (Chrome & Firefox) and still the same problem!
Thank you for your help.

Hello Tufiq,
I just reverted to PHP 7.4 and it actually works.
But Joomla recommends upgrading to PHP 8.0.
In addition, my hosting will make me pay for the PHP 7.4 version if I stay on it.
Thanks for your feedback.
