No issues were found from a basic inspection of the plugin. The plugin does use WordPress storage and perform file functions, so the using site will need to ensure this works with the specific infrastructure in place, but standard WordPress storage locations are used so issues are not generally expected. Note that only the core plugin code has been inspected (not the individual content types which are added on demand).
Users of the plugin should consider accessibility requirements and providing an alternative, accessible version for interactive content provided by H5P. The using site has the option to disable backend usage reporting to H5P, which may be considered.
Reason for the 'Use with caution' result
The plugin has been given this recommendation at the tester's discretion:
No issues were found from inspection. As at 17 January 2023, the official plugin page does report that it is not tested with later versions of WordPress, which may be a concern. A support query has been raised to clarify. In addition, the individual content types made available should be checked by the user, particularly for accessibility concerns.
