I hope somebody can help me. Last week I was restyling a design I made earlier. After some changes I noticed that there was a horizontal scrollbar at the bottom of the page, even with all the content fitting the container div.
I thought it was my mistake, by editing some CSS in the wrong way BUT today I was checking the original site that didn't have this scrollbar and all of a sudden that website as well had the horizontal scrollbar, without changing anything to it's css, and without updating any plugins.
You can check the sites out at talal(dot)green-life(dot)be --> that's the redesign. Or take a look at www(dot)in-malle(dot)be for the original.
I hope somebody can help me or had the same problem once... I really need a solution :)
For whatever it is worth in solving the problem: the custom.css and reset.css files are not accessible. You will know best how these may relate to your issues. I just finished troubleshooting a similar issue a few weeks ago, after some changes. At the time, I wasn't smart enough to document the specific changes, and the order in which they were executed. (Never again! The time to document is far less than the time required to fix ... at least for me). What I ended up doing was determining the effect that recently added elements had on my fixed width site. Turned out to be a positioning issued with a some social bookmarking buttons. I wasn't able to address that issue until I discovered that removing that element restored the site to a fixed width without a horizontal scroll bar. Good luck.
