A large number of prompts similar to the following will appear when you enter the website, but they can be displayed and run normally.

Notice: Use of undefined constant ctbTitle-assumed ctbTitle in d: ctb1.5ctbincludeconfig. php on line 23...

B answer: these are PHP prompts rather than errors. PHP itself can be directly used without declaring the variables in advance, but a prompt will be prompted if the variables are not declared. Generally, when a website is a formal website, it will turn off the prompt and even the error message.

How to disable PHP prompts

Search for php. ini:

Error_reporting = E_ALL

Changed:

Error_reporting = E_ALL &~ E_NOTICE

There is another way to do this:

Add each file header

Error_reporting (0); the problem can be solved even though it is difficult to solve.
