Windows7 and XP + explorer8 and 9

Vilho

Hello, something (probably done by us) has caused our Superior to be incompatible with older IE browsers that are used from XP or Win7. Operating system that is browsing with IE8 or IE9 is does not appear to show the page as it should. Also with XP with IE9 is almost unreadable. My site is located at https://www.asuntojenmyynti.fi.

There has been some changes where we have tried to speed up our site. These tweaks have included CSS and HTML optimisations.

Currently WordPress 4.2.2
Superior version 2.0.2

Hello there:-)

For start I see you have some JavaScript errors, and it can be seen even in firefox or chrome console.

On your place I would remove all caches and compressions, and check on each step when page will start to work on IE 8, cause now it indeed has no styles, and it could be caused by too big files after compression, cause both IE 8 and IE 9 have bugs in that matter.

Hope this will help you start hunting down issues.

With kind regards.
