I installed 5.3.2 WP but the editor is not functioning. The editor field does not show the content, and I’m not able to add new content because of it. The only plugin that I have is the default one. What could I do to fix this problem?
I discovered WP 5.3 installed a competitor’s plugin and removed the links for me to access your Classic Editor plugin.
I removed both plugins to solve the issue.
Next I put Classic Editor back in the plugins folder, refreshed, and all is back to normal – excellent!
BTW on their page on this site, the Classic Editor Addon developers make comments against Classic Editor which I felt uncomfortable reading.
Check the following link it has the solution and why
