If your site takes a long time to load and finally you get an error that it’s not available, that means your connection has timed out.
This simply happens when your site is trying to do more than the server can handle and is particularly common in shared hosting environments with limited resources.
Solution
There are a few things you can do to solve this:
- Deactivate all plugins — Plugin problems can also cause timeouts. Refer to the description above to find out how to fix them.
- Switch to a default theme — Timed-out connections are also sometimes due to theme issues. In this case, follow the instructions further up on the page to use one of the default WordPress themes.
- Increase your PHP memory limit — We also already talked about how to do this and it is another possible solution for this common WordPress problem.
If neither of the above does the trick, please create ticket from your client area.
