Operation prompts such as WordPress adding and updating database report error


I haven’t moved the layout in WordPress for a long time. After planning for a long time, I decided to change the layout today. However, when I add and update, I repeatedly report an error. The error information is as follows:
Fatal error: Unknown: Cannot use output buffering in output buffering display handlers in Unknown on line 0
I’m very depressed. I don’t know what the problem is, because I’ve used these operations for a long time, but I usually add the next article. How can I report an error! Think it’s the space provider’s problem! After struggling for half a day, I finally had to ask Google for help. I found it!

I saw it on the Internet
Disable your plugins. If the problem goes away start re-enabling them on by one until you find the problematic one!
Disable the installed plug-in, if the problem is not solved, enable it, and then disable the next one, until the problem is solved!
I started to operate with a try attitude, but I didn’t expect it to be true, because I installed a code highlighting plug-in before, and the plug-in didn’t produce any effect, but I got this problem! It’s OK to solve it. Share it! Ha-ha!
