Installation and server related problems

Hi

I just installed the version 1.15.5 of H5P, on wordpress (v 6.1.1), and php version 7.4.

I am  trying to create a add a new content but it doesn't load the tools, and stay blank (see image)

Im using query monitor and doesn't show any error,

on php-error.log shows

[13-Dec-2022 13:44:09 UTC] PHP Deprecated: Function spacious_options is <strong>deprecated</strong> since version 2.5.0! Use get_theme_mod instead. in /data/wordpress/htdocs/wordpress/wp-includes/functions.php on line 5383  

Dear all,

I have installed the H5P plugin in our WordPress (5.4.12).

I can only upload activities of +-7,5 Mo but I can't upload my H5P activities of +- 80 Mo.

The maximum upload speed of our server as well as WordPress are correctly configured.

I deduce that the problem comes from the plugin, is the H5P plugin of WordPress also affected by the 16 MB restriction as for H5P.org ?

How can I upload my larger activities via the H5P plugin?

Thank you for your attention to my problem.

Kind regards,

Hi, can I honestly ask for any "simple" OR "readable" guide for installing H5P into PHP Coded application?

I'm trying to use it as my University project and integrate H5P to app for creating educational materials.

Thanks for sharing, if you found one. <3
