Today the media image editing function in my wordpress site suddenly had the problem of not being able to save the edited image, checking the console, and finding that the admin-ajax.php page reported a 500 error. To be safe, wordpress will disable the debug function by default, but there is no specific error description, the subsequent debug can not be carried out at all.<\/p>\n\n\n\n

To find the exact reason for the error, I logged into the server<\/p>\n\n\n\n

Open wp-config.php in the wordpress root directory.
locate<\/p>\n\n\n\n

define('WP_DEBUG', false).<\/code><\/pre>\n\n\n\n
modify to<\/p>\n\n\n\n
define('WP_DEBUG', true);\ndefine('WP_DEBUG_LOG', true);<\/code><\/pre>\n\n\n\n
\"\"<\/figure>\n\n\n\n
<\/p>\n\n\n\n
Enable debug mode in wordpress, the second sentence means that by enabling WP_DEBUG_LOG, users can save all errors in the debug.log file<\/p>\n\n\n\n
The debug.log file is in the \/wp-content\/ folder<\/p>\n\n\n\n
On the frontend media page, re-edit the image and save it<\/p>\n\n\n\n
Then look at the contents of the debug.log file<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
<\/p>\n\n\n\n
Here you can see that it is the aliyun-oss plugin incompatibility with the new version of wordpress that is causing the problem<\/p>\n\n\n\n
Uninstalled the plugin, problem solved<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
<\/p>\n\n\n\n
Finally, don't forget to turn off debug mode<\/p>\n\n\n\n
