  Nebojsa Djukic: I've just checked Google cache of one of my sites. It looks terrible. No images, no CSS, no fancy WP theme... Just naked text and hyperlinks. ;
  
  What could be the reason? WP theme, a caching plugin...?
• 
  Edwin Jonk: My guess is that your robots.txt is blocking the css. But I need to have an URL first. Can you share an URL?
• 
  Nebojsa Djukic: For some paranoid reasons ;I'd rather not share the URL. However, here is the content of my robots.txt:
  
  User-agent: *
  Disallow: /wp-admin/
  
  Sitemap: http://my-site..va/sitemap.xml

  Neeraj Pandey: Could you go and check in Search Console?? try to do fetch as Googlebot and see what the look google showing it also check in " Blocked Resources" that will be displayed below..
• 
  Nebojsa Djukic: +Neeraj Pandey ;Just checked blocked resources and nothing appears blocked. ;
  
  Fetch as Googlebot - pages looks just like cached versions.
  
  Google cache of some of my pages on the same site looks normal (with css, images etc), some pages are with images but no css and the rest is without images and css.
  
  Any ideas?
• 
  Neeraj Pandey: Could you provide us some shortened url?? in case you don't want your website url to be published??
• 
  Edwin Jonk: Just another guess. If you changed your theme or the URL to the css, and the page hasn't been crawled yes, it can happen. ;
• 
  Nebojsa Djukic: I have a few similar sites, but just with another WP theme. Those sites are ok. I switched to another theme and disabled a caching plugin. Let's wait for a few days to see if there will be improvements.
• 
  Nebojsa Djukic: Just noticed that I have a plugin with the following description: "Optimizes your website, concatenating the CSS and JavaScript code, and compressing it." - that one is highly suspicious. Disabled, deleted, burned.
• 
  Nebojsa Djukic: A few pages are cached today and they looks normal. So it was about a theme or caching plugins I used.

  Dave Elliott: Allow your wp-admin folder. You shouldn't be blocking that these days
