Just installed a fresh copy of WP 3.1.3 on an add-on domain thru Softaculus @ my hosting company. I have a primary domain and a separate add-on domain (completely unrelated domain names) that installed WP thru Soft the same way with no probs.
On this domain/install however, I find that my dashboard is missing the usual WP icons (along the left side menu) and the rating stars on the plugins page look positively funky (yellow highlight and such).
I’ve tried deleting everything and re-installing but no dice. The site used to be an inactive blogger blog w only one post (all deleted now) – but I’ve checked and rechecked DNS etc. (all seems to be fine) and as I say, I’ve installed WP with others through this hosting account without any problems.
