Domain still pointing to your old server? – check that Cloudflare A records (for “domain.com” and “www”) are pointing to the right server IP. You can also use DNSchecker.org to see if the new DNS records have fully propagated across the internet yet (maybe your local ISP is still slow). Or maybe it’s just your local computer with old DNS cached; you can try clearing browser cache, opening incognito window, use another browser, or use another computer, or even another internet connection. Some people may also get around by temporarily configuring their router to use Cloudflare DNS instead of their local ISP DNS.
White screen of death (WSOD) – there’s probably a PHP error somewhere. You can try looking at error logs in your web directory or also the “logs” directory. You can also try lower your PHP version from cPanel > MultiPHP Manager.
Website links or assets pointing to the wrong domain – you have to update your URLs in the database using Better Search Replace plugin.
Only homepage works but other links don’t (404 or error pages) – go to WP admin > Settings > Permalinks and click “Save Changes”, then do it again for good measure.
Cache issues – try deleting old cache files from such as the “advanced-cache.php” and “object-cache.php” from the wp-content directory. Also delete everything you see in the wp-content/cache directory. It might help to re-install your cache plugin as well. We recommend LiteSpeed Cache or Swift cache on our servers.
Any other weird issues? – look in your htaccess file and clear out anything weird or from your old server; you can also try backing it up and using only the default WordPress lines just to see. Can also check your wp-config.php for anything weird or configurations from your old server. You might also want to try disabling your plugins to see if any of them are causing issues. Sometimes, plugins aren’t compatible or just need to be re-installed on the new server. To disable plugins one-by-one, go to “wp-content/plugins” and rename a plugin folder (try changing “Jetpack” to “1-Jetpack”). To disable all plugins at once, go to the “wp-content” directory and rename the entire “plugins” directory to something like “plugins-disabled”.
