The
iframe resizer lib files will be updated to the latest available release because it fix several issues
https://github.com/davidjbradshaw/ifram ... r/releases
(
https://github.com/davidjbradshaw/ifram ... tag/v5.2.0)
There is no problem on using the old
iframe-resizer.child.js with the new
iframe-resizer.parent.js that will be automatically included when the plugin will update, anyway to have all fixed to the latest and get all benefits, the
iframe-resizer.child.js file should be replaced by the new one that can be found into the folder
/wp-content/plugins/wp-w3all-phpbb-integration/addons/iframeresizer/iframe-resizer.child.js
The phpBB template require to be recompiled, if the file
iframe-resizer.child.js will be updated with the latest one included on the next 2.8.9 (or the cached one will be used until the template has not been updated).
Anyway, as said, the code will follow working fine even with mismatching parent/child versions.
