It still happens to me everytime I come on this site, and only this one. I did some Google research and they said that there could be a programming error on the site that our computers recognize or something. Funny that it started right after they made some changes to the site.
It's very annoying that's for sure!
We haven't made any changes to the forum software and we haven't noticed any errors. I would need a screen shot of the error message and the browser version you are using to look at this.
We did find one java script that needed to be updated and we fixed it. It only was aproblem in certain browsers. Hopefully this working for everyone now, but if not please let us know.
