My geek sons have been helping me with some work on my site. All was going well until yesterday morning when the site suddenly wouldn't load. (Just get a blank white page in browser, though correct URL displayed in address bar.) It was loading OK the previous night.
I checked with my host's support. They said the domain (or sub-domain to be precise) is loading fine from their end. They suggested it might be an incompatible plugin. Then they observed that it seems to be an issue with the www. string - i.e public page loads without the www. but not with it. (However admin won't load either way, so nothing I can do about plugins etc.). In connection with that they suggested it
may be an issue with the .htaccess that is included with your WordPress site.
I'm too noob to understand what the .htaccess file does or what its contents might mean. (Actually my host support added it in for me a couple of years ago to address some other issue at the time.) But I can report that removing it from my blog folder makes no difference either way to this present problem.
Can someone suggest something I could investigate? Thanks.
