I've installed SugarCRM (5.5.4) and everything went fine. Ran the chmods according to the installation docs, and I'm not seeing any errors in my Dreamhost apache error_log. I don't think it's a permissions issue in the cache, which a lot of my googling points to, because it isn't fixed even if I set the entire SugarCRM directory to 777 (no, I don't leave it that way This is on a Dreamhost shared server.
However, my browsers are giving me fits. Sometimes they render the CSS, but often they don't, which makes the pages unusable. If I clear the cache, restart the browser, etc. I can sometimes make it work right. That's on Firefox, IE, Safari on a couple different boxes.
I'm wondering if there is some Dreamhost setting that is interfering...? I'm really not sure what else the issue could be. I don't have any other issues with any other web app on any other site.
