Hello to the community. I hope you can help me or give me solutions.

Today I modify the .htaccess to manage the browser cache and improve performance of the site but it crashed the site. I put the backup of .htaccess but the error persists.
Here is the error displayed :

Warning: scandir(/var/www/clients/client9/web40/web) [function.scandir]: failed to open dir: Permission denied in /var/www/clients/client9/web40/web/sapphire/core/ManifestBuilder.php on line 196

someone has an idea?

Thank you in advance

I tried, without success.

As the problem is triggered after handling.htaccess, I wonder if my file is correct. Here it is:
