The editor will share with you how to troubleshoot the 500 errors prompted by opening the website. I believe most people don't know much about it, so share this article for your reference. I hope you will learn a lot after reading this article. Let's learn about it!

Generally, 500 errors are caused by the following problems

1. The pseudo-static rule is incorrect

The 2.php version is not compatible with the website program

3. The website cannot connect to the database (that is, the database profile of the site is not configured or misconfigured)

4.php disables a function and needs to be enabled.

5. The site needs to access the off-site directory, and anti-cross-site processing needs to be turned off.

6. The source code itself has BUG

According to the tutorial, turn on the php error prompt to see what causes it.

First select the php version used by the site

Error message to turn on php

Modify the configuration file to change display_errors = Off to display_errors = On

Restart php after modification

Note: pagoda php installed before July is off error by default, and is enabled by default after July.

After opening it, you will see prompts for what files, how many lines and what goes wrong.

You need to check the source code yourself

If you open a web page and show a blank screen, nothing will be shown.

Modify the php configuration file to raise the error level to a minimum to display all errors

Modify error_reporting= E_ALL & ~ E_NOTICE to error_reporting= E_ALL

Then restart php.

Note: if the website can be accessed normally after debugging, please turn off the error prompt.

Just change display_errors = On to display_errors = Off.
