A series of issues.

Bugs with "indentations," the "edit" button, and "database issues" occur simultaneously and are accompanied by a message at the bottom of the screen that reads as follows.

In addition to the above-mentioned bugs, there are messages from a "missing user."
That is, a user writes a message at a certain time, but the forum says that this user was on the forum "so many" hours/minutes ago... That is, the message was left, say, at 3:00 PM, but the user was supposedly last on the forum at 1:00 PM...

Added 8 minutes later
Right now (when I'm writing this message), everything is fine: the quote indentations are correct, the edit button works, and the database is okay. There are no database error messages. Although just 15 minutes ago, everything was glitching.
