There are tons of PHP notices. Obviously these don't show up in production, but they're very annoying and make navigating the site locally quite difficult. Some of the affected pages: - Search Engines - Browse _______ - Add-on display page (2 warnings if no reviews/discussions)
I do think this problem does not exist anymore (at least I don't get notices on my local dev copy). Please reopen if I am wrong.
The search engines page has a ton of notices, and add-on display pages have a foreach() warning.
I had a new version of the search engines page in my tree but I thought it was going away with 3.2 and bug 409076 so I didn't check it in. I think this is still the case.
I do believe this is fixed in 3.2. I haven't noticed any PHP warnings lately, which speaks for the quality of code, I guess :) Please make a new bug if you notice specific warnings so they can be fixed.
