 if ( w3all_onclick_smile === false && w3all_onview_attach === false ) {
   if ('parentIFrame' in window) window.parentIFrame.scrollTo(0,50); // change 50 to another value may 0 or 100 or 500. Top distance gap in px when page scroll top
  }

fix correct scroll gap space from top, to fix different WP themes header heights.
This fix has been already applied on the online how to [i][url=https://www.axew3.com/w3/2016/02/embed-phpbb-into-wordpress-template-iframe-responsive/]overall_footer.html[/url][/i] code, that has been a little bit changed:
[code] if ( w3all_onclick_smile === false && w3all_onview_attach === false ) {
if ('parentIFrame' in window) window.parentIFrame.scrollTo(0,50); // change 50 to another value may 0 or 100 or 500. Top distance gap in px when page scroll top
}[/code]

if you like to update, remember to recompile phpBB template.
More fixes are coming and logged here in the while, so all added on next 1.9.3 version, if any bug to be fixed to report, follow here

window.onload = function() {
var pmn = "{PRIVATE_MESSAGE_COUNT}";
var w3all_phpbb_u_logged = "{S_USER_LOGGED_IN}";
// to send to wp at once here, like this: #w3all_phpbbpmcount=val#w3all_phpbbnotifycount=val#etc etc etc
var w3appendevents = '#w3all_phpbbpmcount=' + pmn + '#w3all_phpbb_u_logged=' + w3all_phpbb_u_logged;
parent.w3all_ajaxup_from_phpbb(w3appendevents);
}

// WoW! fix vertical align on viewtopic.php or preview, where # anchor etc
$(window).load(function() {
var bd = document.getElementsByTagName("body");
for (var i = 0; i < bd.length; i++) { 
    var bdID = bd[i].getAttribute("id"); 
}
var elt = document.getElementById(bdID);	
elt.setAttribute("style", "position:fixed;top:0%;left:0%;width:100%;");
});

Time to improve a little bit the iframe mode. I'm around to fix all things about this time on these days

It was a bug about iframe i aimed from long time, the problem for example was coming out by clicking the link to view a last post which link point to phpBB viewtopic.php, where there are many posts to display, or maybe an inline image to display like this post) the result was this:

[attachment=0]wrongTop1-forum.jpg[/attachment]

[b]instead than the correct vertical alignment of the iframe, like this:[/b]

[attachment=1]correctTop1-forum.jpg[/attachment]

the solution seem to be this:
[b]open [i]overall_footer.html[/i][/b]
where added the iframe resizer code, search for this:
[code]window.onload = function() {
var pmn = "{PRIVATE_MESSAGE_COUNT}";
var w3all_phpbb_u_logged = "{S_USER_LOGGED_IN}";
// to send to wp at once here, like this: #w3all_phpbbpmcount=val#w3all_phpbbnotifycount=val#etc etc etc
var w3appendevents = '#w3all_phpbbpmcount=' + pmn + '#w3all_phpbb_u_logged=' + w3all_phpbb_u_logged;
parent.w3all_ajaxup_from_phpbb(w3appendevents);
}[/code]
just after, add this code:

[code]// WoW! fix vertical align on viewtopic.php or preview, where # anchor etc
$(window).load(function() {
var bd = document.getElementsByTagName("body");
for (var i = 0; i < bd.length; i++) {
var bdID = bd[i].getAttribute("id");
}
var elt = document.getElementById(bdID);
elt.setAttribute("style", "position:fixed;top:0%;left:0%;width:100%;");
});[/code]
Recompile phpBB template.
Even if it work and has been applied on this online example it has not been still added into [url=https://www.axew3.com/w3/2016/02/embed-phpbb-into-wordpress-template-iframe-responsive/]overall_footer.html help page[/url] code.

The complete fix will be added on code of the procedure with all hints as soon tests finished. If any cool hint by someone about this would be nice ...
