Can't generate Sitemap

[simone_romeo]

Greetings, I'm using Magento 1.9.4.1 C.E.

I need to generate a Sitemap for my website www.cosedelposto.com.

If I do System - Configuration - Google Sitemap it gives me a 404 Error.

If I do Catalog - Google Sitemap (Extended) - Generate - Generate then I get a 500 Error.

What can I do?

Update: I found out that the error is caused by an extention, but I do not know which one. How can I disable them all one by one to discover which is it?

Hello @simone_romeo 

Try disabling extension from config.php file

inside app/etc/

Replace 0 instead of 1, whichever extension you want to disable.
