PHPCMS recommended bits display garbled

The

site moved from the old server and was basically normal after setting up, but only the tweet field became garbled.

went to the background of the "push bit management" and found that the title even the article has become garbled, but the link point into the original text coding is normal.

Home page garbled:

:

the coding of the whole site is normal, only the module related to the "recommended bit" has a coding exception.
guess that you should modify the code from the php block of the recommended bit module?
but I don"t know the location of the file
. Do you want to ask the forum friends for any suggestions?

Thank you in advance!
