Hello!
2.7.4 has been released but let me say, it has been released to mainly fix two aspects:
the fact that the admin config page was throwing Php warnings, when WP in debug mode, because containing deprecated php.
It has been all updated/fixed about his aspect.
While about the iframe integration, the code of two plugin files:
/wp-content/plugins/wp-w3all-phpbb-integration/addons/page-forum.php (the page that become page-(whateveryouwant).php into your active template folder)
and
/wp-content/plugins/wp-w3all-phpbb-integration/views/wp_w3all_phpbb_iframe_short.php
has been updated to
REMOVE the use of the
JS deprecated document.domain
and so to fit the new
overall_footer.html JS code:
https://www.axew3.com/w3/2020/01/phpbb- ... iframe-v5/
But the code is still away to be perfect: it works as you see here, but it is still necessary to improve the smooth scroll behavior in some circumstances and more: the overall_footer js code, need to be re-ordered to be executed at the right time, so to have a smoother and precise flow, and it will be done on next coming release.
You can follow on use the old code if you want, or reload the page-board with the new one and the overall_footer code to update to the new postmessage way that replace the deprecated document.domain.
If any problem just post
