Saving file overwrites PHP

======== TEMPLATE BUG FORM ========

Wappler Version : 2.4.5
Operating System : Windows 10

Expected behavior

Saving a file should not change the code

Actual behavior

The small piece of PHP code below is overwritten

How to reproduce

Append a dynamic version string to an image file like this:
<img src="images/image.jpg?v<?php echo filemtime('images/image.jpg');?>">
…and save the file. Wappler rewrites the code like this:
<img src="images/image.jpg?v+++++++++++++++++++++++++++++++++++++++++++">

Is that the only php that you have in the document?

Yes.
