Fix Course Titles that show up with codes

It was found that the Course Title was displayed with codes.

The dynamic content is built by a section of custom codes.

Since the course data is part of the IntraApps that uses tables that are not part of the standard WordPress, its connection to database was checked first. And found that the IntrApps itself was not matched to the new server. Fixed that database connection first.

Then digging into the custom codes, it was found that current server environment requires a more stringent PHP coding standard.

After modifying related codes to meet the requirements, Course Title is then displayed as expected.
