Yoast Sitemap – Stylesheet Error

Hello there fellow WordPress users.

I’ve just started getting into this world but I’m loving it, many new things to learn and damn I’ve been reading a lot! While I’m happy with my progress so far I have the need to ask for help since I’m unable to figure this problem out.

I’m using the “WordPress SEO by Yoast” plugin to generate my sitemap but while it seems to work correctly on Chrome I get the following error in Firefox:

Error loading stylesheet: An XSLT stylesheet does not have an XML mimetype:https://www.gamingsurvivalist.tk/main-sitemap.xsl

And in Internet Explorer instead of appearing correctly I see the following line of text:

https://www.gamingsurvivalist.tk/post-sitemap.xml 2013-09-10T12:54:24+00:00 https://www.gamingsurvivalist.tk/category-sitemap.xml 2013-09-10T12:54:24+00:00 https://www.gamingsurvivalist.tk/author-sitemap.xml 2013-09-04T20:54:31+00:00

I’ve had some compatibility issues with the yoast sitemap and W3 Total Cache and as such I removed it and cleaned my .htaccess file but I don’t think that can be related. It seems to be an error regarding the way the sitemap appears to users but does it also affect the sitemap crawling or SEO? And why the hell is it working on Chrome?

I would appreciate any help.

Thank you.
