I have used Sourcerer for years. My site got hacked on Thanksgiving and I have had to re-construct it on a new server. Now using all the latest Joomla 4 (4.2.5), PHP 8.1, MySQL 8 and so forth.
Renewed my subscription for Regular Labs and installed brand new Sourcerer and its download key.
When I try to implement {mp4remote} to play a remote MP4 video, instead of the video appearing within the news article, just the typed out line with {mp4remote} codes appears.
