Finally, I think I got it!!!
You probably haven’t gotten it all out of your site. I found several hidden .htaccess files in other folders. there is also this folder in your wp-includes called ‘pomo.’if you see a pm.php file, remove it. The only files that should be in that folder are: entry.php, streams.php, translations.php,po.php and mo.php. Update everything (all plug ins and wp updates.) My site is now loading properly on mobile devices. Those hackers are tricky. Hope this helps! If you have any questions or if I can help you, I’d be happy to.
I’m having the exact same problem. If anyone can offer any assistance, we’d be greatful! Thanks!
