How come when I try to go on the grass city forum from my laptop it says invalid URL?? It works fine on my iPhone though.
You may be entering the URL in wrong? You could have the site blocked somehow, but I don't think it would show a URL error for that. You should be asking here Forum Tech Questions, Problems and Troubleshooting - Grasscity.com Forums
Why did you post this in Pandoras? We have a whole forum for technical questions like this one way down at the bottom under Feedback.
