Please update your bookmarks to https://getodk.org/xlsform/. It looks like there is a problem right now with the opendatakit.org website certificates (and redirects) but the ODK resources have all been moved to getodk.org and should be unaffected if you navigate directly to the new URL.
In setting up the redirects, I used email verification instead of DNS verification. Our SSL provider sent the cert emails to accounts that aren't forwarded, so I missed the cert renewal.
I've switched the domain to DNS verification so certs renew automatically. I've also made sure email forwarding works for the common accounts (abuse, admin, contact, email, postmaster, tech) so any other incoming emails are not missed.
I have updated my bookmark to the new path but i am not able to use the previous compiler " previous version (v1.x)." like before . I do not want to use the current one as it is not behaving well on the repeats is there anyway the previous compiler can be enabled or where i can get access to the offline version of it
