I received an error in the log:
...\includes\sqlhandler.inc.php line 738
$sanitized_input = "
$name = '$value'";
(Array to string conversion).
1. I incorrectly added the video. I inserted the video through the iframe code. In the Video Type section, I did not specify anything, I forgot, the default is File.
2. After editing, when I clicked the Save Video button, I received this error. Also in this video, after editing, the Screenshot disappeared.
The day before, there was a similar case, the video completely disappeared. In phpmyadmin, there was a line with this video, but there was no video on the site. Maybe it's something related to the sessions ... I did not immediately edit these pages. I clicked the edit button and spent some time doing other things. Well this is so for information.
