Record wordpress background appears button click no response solution, and background error TypeError: Cannot read properties of undefined...
situation
A few days ago, there was no response when I clicked the edit button on another computer
Later, I found that this problem also occurs in my own computer.
And this has been the case for several days in a row.
So I turned off all the plug-ins and found that it was back to normal.
So after trying one by one, I found that it might be a conflict with the wpjam plugin
Then I asked the author, and the author said that it might conflict with the theme, but after changing the theme, I found that this is still the case
And this error will appear in the console output
Considering whether the content of the wp file or the cache was changed, I simply backed up the database and reinstalled it directly.
After reinstalling, I removed the cdn, installed the plug-ins that might have conflicted, and found that everything returned to normal
Later, after installing the CDN, it seems that an error was reported again, which may be a problem with the CDN.
So I asked Tencent Cloud customer service and they said it might be a cdn configuration problem,
Be sure to ensure that wp-admin is not cached, so refresh the cache and clear the browser cache, everything will return to normal
