Certificate verification failed error help me

Hello , my problem is

It looks like you're missing format.sh. I would suggest giving a bit more information and in a more readable format.
What steps did you take that led to this error?
Are you using apache? nginx? Something else?
Generally you create a CSR, provide it to the certifying company (too hard to read in your screenshot for my old eyes, I repeat, cut and paste into your question), they give you a cert and usually an intermediate cert. You then place those certs and private key somewhere, and reference them in a configuration file. I'm not familiar with format.sh but goign through the steps you took to install the cert might help.
Hello my friend this problem is solved only 1 i got it clone, its sitemap gives error in summer
From which folder do I change the certificate?
Is this for a web server? You should probably have a file somewhere which points to where the cert is. For example, in typical apache vhost configuration it might be something like

  SSLEngine on
   SSLCertificateFile /usr/local/etc/apache24/ssl/mycompany.com.crt
   SSLCertificateKeyFile /usr/local/etc/apache24/ssl/mycompany.com.key
   SSLCACertificateFile /usr/local/etc/apache24/ssl/intermediate_new.crt
IMPORTANT: That's just an example, you might have your certificates in any place or chained into a .pem file. The point I'm making is that in most web servers, there are configuration files where you tell the server where to look for your certificate.
