Support > Knowledgebase holds articles on hosting, domains, email, security and billing.
SEARCHING IT
Use the search box with specific terms. "wp-cron" or "error establishing a database connection" finds more than "website broken".
Browse by category if you are learning rather than troubleshooting. The cPanel and Web Hosting categories are worth reading through once when you are new.
WHY IT IS WORTH CHECKING FIRST
Most common problems have a documented answer that resolves them in minutes, at any hour, without waiting for a reply. Articles also carry the specifics of our environment, such as the blocked HTTP wp-cron, which generic advice found elsewhere does not.
IF AN ARTICLE DOES NOT SOLVE IT
Open a ticket and say which article you followed and what happened. That tells us immediately what to skip.
IF SOMETHING IS MISSING OR WRONG
Tell us. The knowledgebase is written from the questions we actually receive, and a gap you noticed is likely one others have hit too.
Articles are updated as our platform changes, so an answer found elsewhere on the internet may be right in general and wrong for our servers.
