Installation and server related problems

Hi

We've been trying to figure out a way to integrate H5P into our School management system for a while now with no success. The system is based on Codeigniter. 

Kindly, let me know if you can help with this or if you can forward me to someone who can. We would've given up on the whole idea had H5P wasn't an exceptional solution that can add a lot of value to the learning process.

Obviously, this is a paid task.
Looking forward to your response.

We have a local moodle server setup to host our H5P content. We embed our H5P content in our Brightspace LMS and use the h5p-resizer.js to handle responsiveness.  It was operating perfectly until we recently updated from Moodle plugin version 1.20.2 to 1.21.0.  The update seems to have broken the h5p-resizer script.  It only happens in Firefox, though. Which is odd.

We have a deveopment server that we reverted back to the older version of the plugin (1.20.2) for testing and the resizing script started working again. If we re-upgrade back to 1.21.0, it breaks.

I am unable to upload my audio wav files for the audio player. It shows it is uploading up to 100% but then I get the error message:

File not found on server. Check file upload settings.

I am working in wordpress with LearnDash and H5P. I am on a Macbook Pro in Chrome Version 84.0.4147.135 (Official Build) (64-bit). 

Suggestions on how to resolve?
