Im new to zymic hosting and i was wondering if .HTACCESS Files were aloud for custom 404 pages, and redirects, i read the Terms of conditions twice, and didn't find anything against it although with my old host they kicked me off for not using their 404 pages is .HTACCESS Enabled and am i aloud to do this?

yes custom 404's are allowed here
