Plain text only appears in firefox older versions… in lastest versions appears this one:
“Error al cargar la hoja de estilo: El procesamiento de una hoja de estilo XSLT ha fallado.”
So…I am going to comunicate with my hosting admins and ask about existing rules blocking XSLT. Let see if I undertood what you said… if I put my sitemap url in Search Console, google spider will recognize it even with this browser error..??
Talking abour rules in server, I have this beautiful .htaccess in wp-content
Order deny,allow
Deny from all
<Files ~ ".(eot|ttf|otf|woff|woff2|xml|css|mp3|mp4|avi|bmp|svg|jpe?g|png|gif|js|html)$">
Allow from all
</Files>
Is it able to interfiere with XSL execution?? I am asking because XSLT is inside this directory.
Thanks a lot..!!! (Non solved yet..!!!)
