Website not showing, email not arriving or SSL acting up – how to find the cause.
13 guides
- My website is down – find the fault step by step Does your website show nothing, an error code or something wrong? Go through the five layers – browser, domain, SSL, server and website – and quickly find the right fix.
- I have changed DNS, but nothing has happened – why? Does your domain still point to the old place after you changed name servers or records? Here's how to see how far the change has got and what you can do yourself.
- The browser says "Not secure" – how to get SSL working Does your site show an SSL warning, a crossed-out padlock or only http? Find out whether the certificate is missing, or whether the page loads content over http.
- I am not receiving any emails – check this People say they have written to you, but the email never arrives? Go through spam, account status, storage, forwarding and MX record in the right order.
- My emails end up in the recipient's spam – how to improve delivery Do your messages land in spam at Gmail, Outlook or elsewhere? Check SPF, DKIM and DMARC on your domain, avoid duplicate SPF records, and fix the content issues that count against you.
- I can't send emails from my email program Does Outlook, iPhone or Mac say the email can't be sent, or does the program keep asking for the password? Check the outgoing server, port, authentication and network.
- Error 403, access denied – causes and solutions Does your page show "403 Forbidden"? Most often the index file is missing, the permissions are wrong or a security plugin is blocking access. Here's how to find and fix the fault.
- Error 404 – page not found Does the front page work, but subpages give 404? Or does the whole domain give 404? Here's how to find out whether the page has moved, isn't published, or the domain points the wrong way.
- Error 500 – internal server error after an update or PHP change Does the page show "500 Internal Server Error" or a white screen? Find the latest change, switch the PHP version back, turn off plugins, or restore safely from backup.
- My website is slow – how to make it faster Is your page slow to load? Measure first, then go for the biggest wins: smaller images, fewer plugins, the latest PHP version, page cache and a CDN where you have one.
- I can't get into WordPress admin Does wp-admin show a white screen, keep sending you back to the login, or have you forgotten the password? Here's how to get back in without losing content.
- Website and email stopped – has your domain expired or not been approved? Did both your website and email stop working at once? Then the domain may have expired, been cancelled or be waiting for approval. Here's how to see it and get things going again.
