    Hi folks

    This is my first time on here. I've had a scout through the topics and can't seem to find anything to help with an issue I'm having:

    I've been developing Thematic child themes (thanks for this Ian, really an amazing job) for clients since the middle of last year. I have a reasonable (though self-taught) grasp of CSS but know next to nothing about php. I've just launched this site for a client:

    and tested it in Firefox (3.5.4), Safari, Chrome and IE back to 5, on XP SP3. All fine (barring the usual IE crud in early versions, although it does render better than the MSN site). The client uses Safari on Mac OSX, no problems there either.

    Some of their visitors however are having horrendous rendering problems, seemingly all in Firefox on XP. Some were positioning issues which I think I've since fixed (double-margins on floats/display inline etc.) but one has completely random styles i.e. no images or backgrounds, calendar text being black on dark grey (instead of white on dark grey), wrong sidebars showing up on certain pages... The other is seeing the original Thematic layout with none of the child theme at all. As they're using the same browser and OS as me I can't for the life of me work out what's wrong, other than their own system/browser settings. It's not even that they have styles turned off as one at least is getting the base level Thematic styles, just no child theme. Am I missing something really basic? Surely if their browser settings were messed up then every site would look bad?

    Apologies if the answer is on here somewhere, I have tried to find it. Any help much appreciated. Screengrabs of rendering issues are available if nec.

    Many thanks

  2. They are running Firefox 3.0 or higher?

    Have you validated your css and html? Sometimes an incorrect character will screw up the display on one browser but not another- and they're very difficult to find without a validator pointing it out.

    Or perhaps it is a caching issue. Have the client click shift-refresh if needed. Here's a screencast for those clients that don't know what refreshing is all about:

    Thanks for the input Devin. I confess I had overlooked validation - my bad, I usually do validate, this was a rush due to deadlines, and I assumed that plugin code would be kosher. There are a bunch of errors, largely it seems from the CSS associated with the iCal Events List plugin and NextGEN Gallery stylesheets, plus some XML errors from me (I'm still based on HTML 4 by default, I keep forgetting to close). As far as browser versions, although I asked for details from the folk that were having problems, all I got back was 'Firefox on XP'. Still strange though, it's fine here on multiple browsers, and I develop on Firefox. I've explained caching, so it's not that. More work needed, back later... (horrible feeling this will be something really stupid ;)

    It was something really stupid ;) Having cleaned up my XML it now validates and everything now apparently works as it should - although one of the people who'd been having trouble tells me they're using Firefox 5! Some of the CSS still doesn't validate, mostly opacity and border radius stuff, so no worries (and nothing to do with plugin code not being kosher). Thanks again Devin for reminding me to be thorough. I'm still confused as to how folk were having trouble when using the same OS/browser as me though...
