I know I can turn off notification each time I visit phpbuilder. But I just thought I'd bring your attention to the problem anyway. As a developer, I prefer to be warned of script errors when they occur. That's the reason I have it on in the first place.
You are correct about the yellow warning sign you get on javascript errors. I don't get it either. But, I do get a ton of those pop ups each time I try to access a page.
The problem is certainly with the code on phpbuilder. You can either try to find the source of the problem and fix it, or you can choose the easy way out and ignore it. It's up to you.
Here is the exact error:
A runtime error has occured.
Do you wish to debug?
Line 87
Error: object expected.
