No Mails visible after update to 1.3.9

[logg-sar]

Hi there

I´ve updated yesterday to 1.3.9 (with some trouble, especcially at database connection. But now its fine)
After logging in I see the folder structure of my mail server but no mails. The mails are here, as i can see with my mail client.

Additionally at logout I get the message

PHP Error: Request security check failed

REQUEST CHECK FAILED

After searching I found the Issue #5579 which suggests a problem with javascript dependencies and points to a bin/install-jsdeps.sh which is no longer available.

Any hint how to fix this?

I forgot
php -v

What version were you using before? Did you check error log? Did you try with disabled all plugins? Check also browser console for errors.

Check also browser console for errors.

This was the correct hint.
The jquery-ui.min.js had - for what reasons ever - wrong user and coundnt be executed.
This lead to this error,

Fixed now.
Thanks

Had same issue. Turning on 'Show Javascript Console' from Safari Develop menu showed me that my Content Security Policy was the problem. Commenting out that in https.conf fixed it.

Is there a recommended CSP for Roundcube?
