@detanatar Hi, it appears that cURL is not enabled and/or properly configured for your site, blocking some of WordPress’ built-in functionality. This is a server configuration issue, and can be the result of your hosting provider’s server maintenance, or when moving to a different hosting provider.
Please see SLB’s documentation for more information on cURL configuration. If you are still experiencing an issue once your hosting provider resolves the cURL issue, please post an update and I would be glad to reopen this ticket and take another look.
@dingdang Please create a separate ticket for your issue, so that the specific cause of the issue are experiencing can be fully evaluated.
