Hi,
I’m very desperate, I have just created a new Package in Module Builder and added several modules to this package.
When entering “Studio” to customize these modules, they do not appear at all.
The list on the left only shows the modules that come with the standard installation, but not a single one of my modules.
I specify, I deployed and installed the modules in Module Loader, But anything appear in Studio 
Any idea anyone ??
please.
Have you Checked file permissions?
Do a quick repair and rebuild from the admin panel.
No, I haven’t checked, where I’m supposed to check file permissions ?
thanks
What is your server set up?
Is it Linux or windows?
Did you try running a quick repair and rebuild?
Run the following commands on the root of your sugar installation.
chown -R www-data:www-data .
chmod -R 755 .
chmod -R 775 cache custom modules themes data upload config_override.php
No, I didn’t try running a quick repair and rebuild, I don’t know how I have to proceed ?
I ran the following commands on the root of my suite installation.
and now ?
please, and thank you for your help 
Run a quick repair and rebuild, its in the admin panel of suite under repair.
