Moodle

Hi All,

We would like to connect H5P with our customized LMS by LTI 1.3, after configureed like below, when access "https://myname.h5p.com/lti/launch", it said "504 Gateway Time-out"

Any idea about this? or do we have any way to get the H5P server side diagnosis logs? 

Hello, the h5p plugin is disabled in default. And it doesn't show up on manage activities. I would like to know how do I enable it in such case?
Moodle version is 3.8.2
What I tried (but not working)
1. Select another theme
2. Clean cache
3. reinstall plugin
Thanks.

\ ce command not recognized within the H5P I installed on moodle:

Hello, I'm not able to write mathematical expressions and chemical formulas inside the H5P that I installed in Moodle 3.8. Before installing the H5P plugin I used to successfully write formulas and chemical reactions in Moodle. For example, the command

  \(\ce{Bi}\)    +     \(\ce{HNO3}\)      \(\ce{->}\)       \(\ce{Bi(NO3)3}\) +  \(\ce{NO2}\) +  \(\ce{H2O}\)
