MyBB SQL Error

I get this error only on the following plugins:
- My Activity
- My advertisements
- CoderME Donation Free
- Latest WordPress Blog Post(s) on your MyBB forum portal
- Profile Design (2.3.0)
- Viglink (1.0)

what can it be, that I get this problem?
Cause the rest of the plugins are working when I install them.

You need to check the error logs to see what the problem is.

In Admin CP -> Board Settings, Server and Optimization Options, Error Type Medium, if it's currently set to "Hide Errors and Warnings", set it to "Warnings and Errors" temporarily, then reproduce the error - it should show you the exact SQL query involved, which usually leads to the culprit.

Without error reports or logging, it's a guessing game.
