  • Linux: F5
  • Android or iOS phone: Swipe from top to bottom

2. Clear the browser cache

Browser cache, a form of cache, allows a website to load faster in your web browser by storing website files (temporarily). However, it can also cause you to still see a 500 server error because the cache has not been emptied. So clear the browser cache by using the following guides:

3. Check PHP error messages

It could also be a 500 error caused by a PHP error. Have you enabled the ‘PHP error messages’ function at one.com? The error message appears in the browser as a file name, line number and a message describing the error. With this function, you can track down and solve the problem.

4. Check the .htaccess file

You give the server instructions with a .htaccess file, such as setting up a 301 redirect. You must use the lines in the file correctly. After all, a typo is made quickly, causing your website to malfunction. So check all the lines in the .htaccess file.
