WordPress background crash and debug mode failure: troubleshooting and solving

The WordPress website background suddenly crashed, showing an "out of memory" error. Even increasing the PHP memory limit is useless, and the debugging mode cannot record the error log. How can this be solved? This article provides some troubleshooting and repair ideas.

The problem is not a simple theme or plugin conflict (excluding), "out of memory" usually implies insufficient memory, but since PHP memory tuning is invalid, the problem may not be on the server side (PHP). The possibility of a browser crash suggests that the problem may be caused by the client (browser).

Troubleshooting steps:

1. Disable JavaScript: This is the key step. Disable JavaScript through browser settings or extensions and try to log in to the WordPress backend. If the problem is solved, confirm that it is a memory leak caused by JavaScript code.

2. Disable plugins one by one: If the problem remains the same after disabling JavaScript, disable the WordPress plugins one by one. If the problem disappears after disabling a plugin, there is a memory leak problem for the plugin. Contact the plugin developer or look for alternatives.

3. Check the theme and core code: If the problem persists after disabling all plugins, you need to check for memory leaks in WordPress theme and core code. This requires a certain amount of code debugging capabilities.

4. Check the browser: Make sure the browser version is the latest version and check if there are any problems with the browser itself. Browser bugs can also cause similar errors.

5. Contact the server provider: If none of the above steps work, please contact the server provider (such as Pagoda Panel Technical Support) for professional help.

Through the above steps, we systematically troubleshoot the "out of memory" error and find the root cause, thereby solving the WordPress background crash problem.
