Internal server error for approving posts

approve post count for my website is set to 0 however after recent update, I need to approve posts of some old members. and also I get the following internal server error:

Error: Internal Server Error
Line: 1
Column: 262166
Window Location:

Unfortunately this does not help us, this is a JavaScript error, the server error that caused it should also be in the logs. We need a backtrace for it and the message.
