Did you acquire a production certificate (not a staging certificate) that covers help.anura7.ca and www.help.anura7.ca? Did you install said certificate?
Please make absolutely certain that the $dataDirectory variable in certsage.php located in the help.anura7.ca directory points to "../../CertSage". When you replace certsage.php with a new version, you lose the changes you made to the old certsage.php.
No certificate covering help.anura7.ca and www.help.anura7.ca can currently be seen in the transparency logs:
A self-signed (snakeoil) certificate (not a Let's Encrypt certificate) is currently installed:
Thanks Griffin: I tried it again, followed the instructions properly. 1. tried the staging certificate. 2. Then, asked the production certificate. 3. Then, hitting the, install button. It has worked with your original PHP file. Earlier, I may have not followed all the 3 steps right. Thanks again, Griffin
