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. https://crt.sh/?q=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.marketbosworthsociety.com
I ran this command: Delete Let’s Encrypt plug-in
It produced this output: Deleted but left residual code
The certificate expired. Would not renew, followed all instructions. Decided not to pursue as moving to new servers. Lat’s Encrypt is not supported so decided to delete plug-in. Plug in deleted but some of my pages have http as they should and some have https which causes a security warning if anyone tried to view them. I just need to know how to remove the residue.
Usually all you need to do is change your WordPress Site URL so that it no longer begins with https://, but instead http://. You already seem to have done that, though.
Any leftover links are likely to be inside your WordPress database.
I found the residue files and renamed them. This time renaming the URL worked The problem is solved, or so it seems. I shall leave it for a week and then delete the files permanently. I was advised that whilst Tsohost do not support Lets Encrypt I can ask for the keys and install them manually. I won’t be doing that. The reason is that I followed your instructions, you can guess that I am no expert, but could not get the certificate to update.
Thank you for your help and support and good luck with your product.
There are a lot of hosting providers that support Let'sEncrypt for non technical-expert users. Some even enables it by default, no need of any configuration. You may consider moving to one of them.
