Frontend editor displays a blank page

Hi Toufiq,
Sorry for the errors, I made a mistake and switched the site to PHP 8.4, which crashed everything!
I switched back to 8.3 and everything is fine, but the blank page issue in the SP Page Builder frontend is still there.
Can you log back in and see where it might be coming from?
Thanks for your help.

Hello Toufiq,
Thank you for your reply.
But what do I need to check on my server so that the page loads properly on the front end?
Any ideas?
Thank you for your help.

Hi Toufiq,
Thank you for your reply.
I checked the hosting (my client is with Amen) and I can't find anything related to ‘mod_security’.
Can you tell me where I should look to disable it?
Thank you again for your help.
Jack

Bonjour Toufiq,
J'ai contacté l'hébergeur du site qui a bien désactivé le "mod_secutity"mais l'accès au frontend ne se fait toujours pas. Quelles autres pistes aurais-tu ?
Merci pour tes retours.
Jack

Hello Toufiq,
Yes, you can back up the site via Admin Tools and install it at home for testing purposes.
However, please set it to noindex, nofollow in the system so as not to harm SEO.
Thank you for your feedback.

Hello Toufiq, thank you for your feedback.
Yes, access to the frontend is working fine on your environment.
The question is why is it no longer working on the client's environment?
For your information, before getting back to you, I also duplicated the site and installed it on another environment where the frontend also worked.
So why is it blocked on my client's hosting, which is with Amen.
What's more, he only works on the pages through this channel, of course!
Thank you for your feedback.

Thank you, Toufiq, for your feedback, but what exactly should I ask my host? At what level does ‘the page generator resources cannot load properly on your hosting’ occur?
Thank you for your help.
