phpBB header is just showing

Hi Mattias, i already answered here:
https://www.axew3.com/w3/2018/01/wordpress-phpbb-integration-without-linking-users/#comment-967

but it’s ok may you not notified about.
so to follow as before,

p.s but in your case i’ve look into output and:
you edited the page-forum.php?
because it seem to me lack of something.
Send me via pm your custom page forum or post into forum, i will take a look.
You done ok phpBB side, but the page forum not add the main resizer js file as i’ve see.
That should be loaded on page by page-forum.php

since it is a php file that you call directly, it can’t be downloaded nor viewed.
Send me via pm at axew3.com zipped.

the file is the default forum file, i assumed you use a custom edited.
Instead here so, seem to be a problem on how the wp theme process the page.
But this is strange.
Substantially, into output of your page-h4ckboard.php header,
after it is processed, there is not this line:
<script type="text/javascript" src="https://www.h4ck.se/wp-content/plugins/wp-w3all-phpbb-integration/addons/resizer/iframeResizer.min.js"></script>
that load the resizer library.
to check that’s true you could try to re-add it this way:
into your template theme header.php file
just before this line:
</head>
add this:
<script type="text/javascript" src="https://www.h4ck.se/wp-content/plugins/wp-w3all-phpbb-integration/addons/resizer/iframeResizer.min.js"></script>
so check if now work.

Strange that this line isn’t resulting on page source output, i’ve not understand why, since the rest of the javascript is parsed and result to be in place.
