Import sections layout doesn’t loas

Hi Qubely support team,
I own Qubely pro, recently (3-4 days)
Everything seems well installed, but when I want to see the library (import layout) nothing loads
it’s like I can’t be connected to the library. Though, my recorded blocks seems to work.
Also, The Qubely global setting in page or post can stay “set up” or can’t be saved, always come back to preset #1.

I’ve tried to desactivate the cache plugin (litespeed cache) and try deactivating all other plugins, nothing changed.
I use the theme Blocksy pro.

Here is my system infos:

Operating System: Linux
Software: LiteSpeed
MySQL version: MySQL Community Server – (GPL) v5.7.37
PHP Version: 7.4.29
PHP Memory Limit: 1024M
