An old SSL certificate appears - empty SSL cache

Web browsers cache SSL certificates to speed up navigation. Normally, it's not a problem. However, when you develop pages for your website or install a new certificate, the SSL status of the browser may hinder you. P.ex you may not see the lock icon in the browser address bar after installing a new SSL certificate.

The first thing to do in this case is to make sure that the domain points well to the IP address of the server (records A and AAAA) and if it is still the wrong SSL certificate that is returned, empty the SSL cache:

• Chrome: go to Settings and click on Parameters Click on Show Advanced Settings Under Network, click on Edit proxy settings The dialog box Internet Properties is displayed. Click on the tab Content Click on Clear SSL status, then click OK. Other leads in this other guide.
• Firefox: go to Background Click on Clear Recent History then select Active connections and click on Clear Now.

Loss of CSS formatting

If the website is displayed without CSS style, analyze the loading of pages with the Browser Console. Mixed content errors related to your styles .css, it may be there, which will have to be resolved in order for them to be reloaded correctly.
