Can somebody help me with this error on my vBulletin 4.2.2 Patch Level 4?

I have found some threads but they have dead links.

Thanks,

This is not an error. This is a hook that is used (beforeunload) in the sites code (might be some other methods as well) to let you know you have some sort of form, comment, field, etc. filled out that has ye tot be submitted.

Vbulletin 4.2.2pl4 is a this point 6 years old. It is also possible that this is/was improperly coded in respect to the newer browsers and how they now handle it. I would seriously consider at the very least updating to 4.2.5 which is 4 years.

Edit:
Quick search found this:

And this. From what it looks like it was an .htaccess issue
