There are numerous similar threads here.
The Web isn't changeless. New techniques are coming, but K-Meleon still uses outdated engine.
General advice is to change old 'stable' 1.5.4 to 1.6 beta (which can be considered as new 'stable release') or even 1.7 alpha.
Try one of the portable builds (some of them are listed in my signature) - they do not have problems with the majority of newest sites. Search through forum for more info about maximizing compatibility with modern websites...
