Analysis error: syntax error, unexpected "endif" (T_ENDIF) in a WordPress theme

Question

This bit of code is for displaying related messages and is located in my include folder.

I recently switched from a local development environment on Mac (using MAMP) to using Windows with WAMP.

Suddenly, this error occurs in this block of code. This did not happen on my local Mac environment, and it does not happen when testing in real time.

Parse error: syntax error, unexpected "endif" (T_ENDIF)

The error indicates the second and last value endif. If I delete it, the same error will be indicated in the code, indicating the last one endif.

Any ideas? I tried to delete both specified operators endif;, and instead it produces the following error:

Parse error: syntax error, unexpected end of file

Answer 1

short_open_tagprobably not included in php.ini. Change:

  <? endwhile; ?>

To:

  <?php endwhile; ?>

And you must change everyone else <?to <?php.
