Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
My domain is:www.myheru.com
We have received an expiry notification but do not have any login details for updating the certificate, as our old supplier is no longer contactable. Does anyone have any advice, as to how we action renewal please?
You need to have access to your web server to start with, you are either paying someone to host that or you are hosting that on a server you run yourself.
Your website is currently using a 1 year certificate from Sectigo (possibly purchased from them or a reseller). Your website is currently running the "Apache" webserver and your content management system is Wordpress. It looks to be hosted by 20i.com
If you're not familiar with how to setup certificates or how to manage your web server you should seek help from a local technical consultant.
