I want to update my WordPress version to 4.0, right now it is WordPress 3.2.1.
When I try to update it, I am getting the below error:
Download failed.: SSL certificate problem, verify that the CA cert is OK. Details: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
Installation Failed
What is the solution for it? Please help me to figure it out.
I am able to resolve this issue by adding below code in functions.php of my theme folder.
I hope this can help someone 🙂
