i need few details:
- Share the video link
- Share the video embed code
Note: wplms do not interfere with wordpress codex. whatever i suggested above is defined in the WordPress codex.
it could be only a third party plugin or js issue. it's also possible that the XHR is not working properly due to server DOS or Delayed response time.
do one thing:
goto wp-admin >> lms >> setting >> disable ajax in unit.
then check.
